Title
MetForm – Contact Form, Survey, Quiz, & Custom Form Builder for Elementor <= 4.1.0 - Unauthenticated Form Submission Exposure via Forgeable Cookie Value
Summary
The MetForm – Contact Form, Survey, Quiz, & Custom Form Builder for Elementor plugin for WordPress is vulnerable to Sensitive Information Exposure in versions up to, and including, 4.1.0. This is due to the use of a forgeable cookie value derived only from the entry ID and current user ID without a server-side secret. This makes it possible for unauthenticated attackers to access form submission entry data via MetForm shortcodes for entries created within the transient TTL (default is 15 minutes).

Title
Unauthenticated File Upload in parisneo/lollms
Summary
A vulnerability in parisneo/lollms, up to and including version 2.2.0, allows unauthenticated users to upload and process files through the `/api/files/extract-text` endpoint. This endpoint does not enforce authentication, unlike other file-related endpoints, and lacks the `Depends(get_current_active_user)` dependency. This issue can lead to denial of service (DoS) through resource exhaustion, information disclosure, and violation of the application's documented security policies.

Classification: TLP:GREEN
Internal reference: DOV-8476
Type: CWE-403 (Exposure of File Descriptor to Unintended Control Sphere ('File Descriptor Leak'))
Component: core
Report confidence: Confirmed
Solution status: Fixed by vendor
Affected versions: OX Dovecot Pro core >=2.3.0 <2.3.22.2, OX Dovecot Pro core >=3.0.0 <3.0.7, OX Dovecot Pro core
=3.1.0 <3.1.6, OX Dovecot CE core >=2.3.0 <2.4.5
First fixed revision: OX Dovecot Pro core 3.0.7, OX Dovecot Pro core 2.3.22.2, OX Dovecot Pro core 3.1.6, OX Dovecot CE
core 2.4.5
Discovery date: 2025-11-25
Solution date: 2026-08-26
Disclosure date: 2026-08-26
CVE: CVE-2026-33263
CVSS: 4.3 (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L)
Details:
submission-login: Panic when mail_max_userip_connections is reached: Panic: epoll_ctl(del, 8) failed: Bad file
descriptor. When mail_max_userip_connections is set (defaul
t 10) and reached, submission-login can crash with epoll() panic caused by file descriptor handling issues.
Risk:
If running in high-security mode (default for community releases), only the new submission connection gets terminated.
If running in high-performance mode (default for Pr
o releases), all connections handled by the submission-login process will be terminated. The crashes can cause failure
for user to send a message, or it can cause duplica
te messages to be sent. If TLS is not used (in the backend server processing the submission), duplicate deliveries
cannot happen, because the crash can only happen at AUT
H stage. No publicly available exploits are known.
Solution:
Limit the number of connections handled by single submission-login process. This has a performance impact though.
Update to non-vulnerable version.

CVE: CVE-2026-33607
CVSS: 4.3 (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L)
Details:
Dovecot IMAP LIST match_sub() Exponential Backtracking — CPU Denial of Service. An attacker that has valid credentials
can use IMAP LIST command to consume CPU.
Risk:
This can cause degradation or denial of service for IMAP. No publicly available exploits are known.

CVE: CVE-2026-27852
CVSS: 7.5 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H)
Details:
DoS by sending mail with bad header. An attacker that can send mail to a user can craft a message whose headers contain
a very large number of email addresses or MIME par
ameters, which causes excessive memory usage when the message is later parsed.
Risk:
The message is still delivered, but reading it over IMAP can exhaust the memory limit of the process and terminate it,
causing denial of service for the affected user. No
publicly available exploits are known.
Solution:
Update to non-vulnerable version.

CVE: CVE-2026-33606
CVSS: 4.8 (CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:U/C:N/I:H/A:N)
Details:
dsync: Mail content can cause dsync protocol injection. Mail content stored by a user can be crafted so that it is
interpreted as dsync protocol commands when an administ
rator later runs dsync with the stream protocol, for example during a migration.
Risk:
Injected commands can modify mailbox state on the destination during migration or replication, including internal
mailbox attributes that a user should not be able to set
directly. It can also cause dsync errors. No publicly available exploits are known.
Solution:
Avoid running dsync with the stream protocol on mailboxes with untrusted content. Update to non-vulnerable version.

CVE: CVE-2026-33604
CVSS: 5.9 (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:H/A:N)
Details:
SMTP Smuggling via Missing Dot-Stuffing After Bare Carriage Return. An attacker that can get Dovecot to relay a
message, for example through Sieve redirect or submission
relay, can use a crafted line ending in the message body to bypass the outbound protection that prevents message
content from being interpreted as SMTP commands.
Risk:
A downstream mail server that hasn't yet fixed the SMTP smuggling vulnerability can be tricked into treating part of
the message body as new SMTP commands, allowing injec
tion of spoofed email. This is the same vulnerability class as CVE-2023-51764 and CVE-2023-51766. No publicly available
exploits are known.
Solution:
Where you control the receiving mail servers, ensure they reject bare carriage returns in message data. Update to
non-vulnerable version.

CVE: CVE-2026-40014
CVSS: 6.5 (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H)
Details:
IMAP THREAD REFERENCES O(N²) CPU DoS via Crafted References Header (index-thread-links.c). An attacker that can send
mail to a user can craft a message header that makes
the IMAP THREAD command consume CPU disproportionate to the size of the message.
Risk:
When a mail client issues a THREAD command on the affected mailbox, this can cause degradation or denial of service for
IMAP. No publicly available exploits are known.
Solution:
Monitor system for abnormal CPU usage, kill the offending process and remove the offending message from the affected
mailbox. Update to non-vulnerable version.

credentials can submit a Sieve script containing an extreme
numeric literal, which causes an out-of-bounds write when the ManageSieve service compiles the script.
Risk:
This causes memory corruption and an observed crash of the ManageSieve process, resulting in denial of service for
script management. This might be able to be used for re
mote code execution. No publicly available exploits are known.
Solution:
Disable the ManageSieve service if users do not need remote Sieve script management. Update to non-vulnerable version.

CVE: CVE-2026-33605
CVSS: 7.5 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H)
Details:
managesieve-login: Pre-auth crash. An unauthenticated attacker can crash the ManageSieve login process by sending a
small malformed command before authenticating.
Risk:
If running in high-security mode (default for community releases), only the attacker's own connection is terminated. If
running in high-performance mode (default for Pro
releases), all connections handled by the same managesieve-login process are terminated. Repeating the attack can cause
denial of service for Sieve script management. No
publicly available exploits are known.
Solution:
Restrict network access to the ManageSieve service to trusted clients. Update to non-vulnerable version.

CVE: CVE-2025-30189
CVSS: 7.4 (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N)
Details:
v2.4 regression: auth cache broken with several passdb / userdb. When cache is enabled, some passdb/userdb drivers
incorrectly cache all users with same cache key, causing wrong cached information to be used for these users.
Risk:
After cached login, all subsequent logins are for same user. No publicly available exploits are known.
Solution:
Install fixed version or disable caching either globally or for the impacted passdb/userdb drivers.

Internal reference: DOV-8349
Type: CWE-20 (Improper Input Validation)
Component: core
Report confidence: Confirmed
Solution status: Fixed by vendor
Last affected revision: OX Dovecot Pro core 3.1.0, OX Dovecot CE core 2.4.0
First fixed revision: OX Dovecot Pro core 3.1.2, OX Dovecot CE core 2.4.3

CVE: CVE-2025-59028
CVSS: 5.3 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L)
Details:
Invalid base64 authentication can cause DoS for other logins. When sending invalid base64 SASL data, login process is
disconnected from the auth server, causing all active authentication sessions to fail.
Risk:
Invalid BASE64 data can be used to DoS a vulnerable server to break concurrent logins. No publicly available exploits
are known.
Solution:
Install fixed version or disable concurrency in login processes (heavy perfomance penalty on large deployments).

CVE: CVE-2025-59032
CVSS: 7.5 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H)
Details:
v2.4/v3.1 regression: Pigeonhole: ManageSieve panic occurs with sieve-connect as a client. ManageSieve AUTHENTICATE
command crashes when using literal as SASL initial response.
Risk:
This can be used to crash ManageSieve service repeatedly, making it unavailable for other users. No publicly available
exploits are known.
Solution:
Control access to ManageSieve port, or disable the service if it's not needed. Alternatively upgrade to a fixed version.

Internal reference: DOV-8584
Type: CWE-200 (Exposure of Sensitive Information to an Unauthorized Actor)
Component: core
Report confidence: Confirmed
Solution status: Fixed by vendor
Last affected revision: OX Dovecot Pro core 2.3.0
First fixed revision: OX Dovecot CE core 2.4.3, OX Dovecot Pro core 3.1.3, OX Dovecot Pro core 2.3.22.1

CVE: CVE-2025-59031
CVSS: 4.3 (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N)
Details:
decode2text.sh OOXML extraction may follow symlinks and read unintended files during indexing. Dovecot has provided a
script to use for attachment to text conversion. This script unsafely handles zip-style attachments.
Risk:
Attacker can use specially crafted OOXML documents to cause unintended files on the system to be indexed and
subsequently ending up in FTS indexes. No publicly available exploits are known.
Solution:
Do not use the provided script, instead, use something else like FTS tika.

Internal reference: DOV-8591
Type: CWE-22 (Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal'))
Component: core
Report confidence: Confirmed
Solution status: Fixed by vendor
Last affected revision: OX Dovecot Pro core 2.3.0
First fixed revision: OX Dovecot Pro core 3.1.0, OX Dovecot CE core 2.4.0
Discovery date: 2026-01-07

CVE: CVE-2026-0394
CVSS: 5.3 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N)
Details:
auth: Path traversal in passwd-file passdb using `%d` (domain) escapes base directory and opens `/etc/passwd`Pre-auth
path traversal in passwd-file passdb using `%d` (domain) escapes base directory and opens `/etc/passwd`. When dovecot
has been configured to use per-domain passwd files, and they are placed one path component above /etc, or slash has
been added to allowed characters, path traversal can happen if the domain component is directory partial.
Risk:
This allows inadvertently reading /etc/passwd (or some other path which ends with passwd). If this file contains
passwords, it can be used to authenticate wrongly, or if this is userdb, it can unexpectly make system users appear
valid users. No publicly available exploits are known.
Solution:
Upgrade to fixed version, or use different authentication scheme that does not rely on paths. Alternatively you can
also ensure that the per-domain passwd files are in some other location, such as /etc/dovecot/auth/%d.

Internal reference: DOV-8775
Type: CWE-90 (Improper Neutralization of Special Elements used in an LDAP Query ('LDAP Injection'))
Component: core
Report confidence: Confirmed

CVE: CVE-2026-27860
CVSS: 3.7 (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N)
Details:
v2.4/v3.1 regression: auth-ldap is not escaping usernames. If auth_username_chars is empty, it is possible to inject
arbitrary LDAP filter to Dovecot's LDAP authentication.
Risk:
This leads to potentially bypassing restrictions and allows probing of LDAP structure. No publicly available exploits
are known.
Solution:
Do not clear out auth_username_chars, or install fixed version.

Details:
v2.4/v3.1 regression: SQL injection allows bypassing authentication. Dovecot SQL based authentication can be bypassed
when auth_username_chars is cleared by admin.
Risk:
This vulnerability allows bypassing authentication for any user and user enumeration. No publicly available exploits
are known.
Solution:
Do not clear auth_username_chars. If this is not possible, install latest fixed version.

CVE: CVE-2026-27859
CVSS: 5.3 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L)
Details:
v3.0.2+ regression: Message headers MIME parameter parsing can cause excessive CPU usage. A mail message containing
excessive amount of RFC 2231 MIME parameters causes LMTP to use too much CPU.
Risk:
A suitably formatted mail message causes mail delivery process to consume large amounts of CPU time. No publicly
available exploits are known.
Solution:
Use MTA capabilities to limit RFC 2231 MIME parameters in mail messages, or upgrade to fixed version where the
processing is limited.

CVSS: 4.3 (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L)
Details:
imap-login: Excessive memory usage DoS. Sending "NOOP (((...)))" command with 4000 parenthesis open+close results in
~1MB extra memory usage. Longer commands will result in client disconnection. This 1 MB can be left allocated for
longer time periods by not sending the command ending LF. So attacker could connect possibly from even a single IP and
create 1000 connections to allocate 1 GB of memory, which would likely result in reaching VSZ limit and killing the
process and its other proxied connections.
Risk:
Attacker could connect possibly from even a single IP and create 1000 connections to allocate 1 GB of memory, which
would likely result in reaching VSZ limit and killing the process and its other proxied connections. No publicly
available exploits are known.
Solution:
Install fixed version, there is no other remediation.

Mitigation
Architecture and Design
Strategy: Libraries or Frameworks
Use an authentication framework or library such as the OWASP ESAPI Authentication feature.
CAPEC-114: Authentication Abuse
An attacker obtains unauthorized access to an application, service or device either through knowledge of the inherent weaknesses of an authentication mechanism, or by exploiting a flaw in the authentication scheme's implementation. In such an attack an authentication mechanism is functioning but a carefully controlled sequence of events causes the mechanism to grant access to the attacker.
CAPEC-115: Authentication Bypass
An attacker gains access to application, service, or device with the privileges of an authorized or privileged user by evading or circumventing an authentication mechanism. The attacker is therefore able to access protected data without authentication ever having taken place.
CAPEC-151: Identity Spoofing
Identity Spoofing refers to the action of assuming (i.e., taking on) the identity of some other entity (human or non-human) and then using that identity to accomplish a goal. An adversary may craft messages that appear to come from a different principle or use stolen / spoofed authentication credentials.
CAPEC-194: Fake the Source of Data
An adversary takes advantage of improper authentication to provide data or services under a falsified identity. The purpose of using the falsified identity may be to prevent traceability of the provided data or to assume the rights granted to another individual. One of the simplest forms of this attack would be the creation of an email message with a modified "From" field in order to appear that the message was sent from someone other than the actual sender. The root of the attack (in this case the email system) fails to properly authenticate the source and this results in the reader incorrectly performing the instructed action. Results of the attack vary depending on the details of the attack, but common results include privilege escalation, obfuscation of other attacks, and data corruption/manipulation.
CAPEC-22: Exploiting Trust in Client
An attack of this type exploits vulnerabilities in client/server communication channel authentication and data integrity. It leverages the implicit trust a server places in the client, or more importantly, that which the server believes is the client. An attacker executes this type of attack by communicating directly with the server where the server believes it is communicating only with a valid client. There are numerous variations of this type of attack.
CAPEC-57: Utilizing REST's Trust in the System Resource to Obtain Sensitive Data
This attack utilizes a REST(REpresentational State Transfer)-style applications' trust in the system resources and environment to obtain sensitive data once SSL is terminated.
CAPEC-593: Session Hijacking
This type of attack involves an adversary that exploits weaknesses in an application's use of sessions in performing authentication. The adversary is able to steal or manipulate an active session and use it to gain unathorized access to the application.
CAPEC-633: Token Impersonation
An adversary exploits a weakness in authentication to create an access token (or equivalent) that impersonates a different entity, and then associates a process/thread to that that impersonated token. This action causes a downstream user to make a decision or take action that is based on the assumed identity, and not the response that blocks the adversary.
CAPEC-650: Upload a Web Shell to a Web Server
By exploiting insufficient permissions, it is possible to upload a web shell to a web server in such a way that it can be executed remotely. This shell can have various capabilities, thereby acting as a "gateway" to the underlying web server. The shell might execute at the higher permission level of the web server, providing the ability the execute malicious code at elevated levels.
CAPEC-94: Adversary in the Middle (AiTM)
An adversary targets the communication between two components (typically client and server), in order to alter or obtain data from transactions. A general approach entails the adversary placing themself within the communication channel between the two components.
