Title
Nodemailer before 9.1.0 Denial of Service via addressparser
Summary
Nodemailer before 9.1.0 contains a quadratic time complexity vulnerability in the addressparser component that allows remote attackers to cause denial of service by supplying a crafted comma-separated address list. Attackers can send a single email with a large number of addresses to block the Node.js event loop for extended periods, consuming 100% CPU and freezing the process.

CVE-2026-92003 (GCVE-0-2026-92003)

Title
MISP Unthrottled Authentication Failure Log Writes Enable Resource Exhaustion
Summary
Affected versions of MISP do not consistently apply the existing authentication-failure logging throttle. Two API authentication failure branches wrote directly to the Log model:  - API requests with no authentication key;  - requests supplying an API key with an incorrect length Unlike other authentication failures, these paths bypassed _shouldLog(), so every request could create another durable auth_fail entry. Version affected: ≤2.5.45

2bf887433651 fix: [logging] Throttle the two unguarded auth_fail writes db6f78e69079…
Fix summary

The fix applies the existing hourly per-key log throttle to the two previously unguarded authentication-failure log writes. The throttle key is now derived from the client's source IP address rather than from caller-supplied input, preventing an attacker from generating unbounded Redis throttle entries. A per-request memo (stored in Configure::read('CurrentRequestAuthFailKeys')) is added to _shouldLog() to prevent duplicate log entries when beforeFilter() executes a second time via CakeErrorController on an exception, ensuring one request produces at most one log entry per key regardless of the operator's log_each_individual_auth_fail setting.

Patch summary

In app/Controller/AppController.php: (1) The 'no authkey' branch in beforeFilter() now calls _shouldLog('noauthkey:' . $this->User->_remoteIp()) before writing the log entry. (2) The 'incorrect length' branch in __loginByAuthKey() now calls _shouldLog('badauthkeylength:' . $this->User->_remoteIp()) before writing the log entry. (3) _shouldLog() is refactored to first check a per-request memo array (Configure 'CurrentRequestAuthFailKeys') to suppress duplicate logging across the double beforeFilter() invocation, then evaluate the log_each_individual_auth_fail setting, then fall through to the Redis EXISTS/SETEX 3600-second throttle, and finally record the key in the memo. The Redis-unavailable fallback (log everything) is preserved.

CVSS rationale

The vulnerable paths are reachable over the network (AV:N) with no authentication (PR:N) and no user interaction (UI:N). The attack complexity is low (AC:L): an attacker simply sends repeated HTTP requests to the MISP API without an API key or with a key of the wrong length. No attack target is required (AT:N). There is no impact on confidentiality (VC:N, SC:N) or integrity (VI:N, SI:N). The availability impact is high (VA:H) because unbounded log writes can exhaust database storage, degrade query performance, and ultimately make the MISP instance unavailable. No secondary availability impact (SA:N) is evident from the patch.

Weakness rationale
  • CWE-770 Two authentication-failure log write paths lacked any rate-limiting or throttling mechanism, allowing an unauthenticated remote attacker to generate an unbounded number of database log entries and exhaust storage or I/O resources. The fix adds the missing hourly per-key throttle.
  • CWE-400 The unthrottled log writes constitute uncontrolled consumption of database write capacity and disk storage, enabling a denial-of-service condition. CWE-770 is the more specific primary weakness; CWE-400 captures the broader resource-exhaustion impact.
Assumptions to verify
  • The tag_version_boundary (v2.5.46, 188 commits after fix) is used as an approximate upper bound for affected versions; the exact fixed release tag is not stated in the patch metadata.
  • The log entries are written to a relational database (MySQL/PostgreSQL) via MISP's Log model, based on the createLogEntry() call pattern; the specific backend is not confirmed in the patch.
  • The Redis instance used for throttling is assumed to be co-located with the MISP application; a Redis outage degrades to logging everything (fail-open), which is a design choice documented in the patch comments.
  • CVSS VA:H assumes that sustained unthrottled log writes can exhaust storage or I/O capacity sufficient to degrade or halt the MISP service; actual impact depends on deployment sizing and disk capacity.

Title
Vikunja before 2.6.0 Denial of Service via Decompression Bomb
Summary
Vikunja before 2.6.0 fails to limit archive expansion during data import, allowing authenticated users to cause denial of service. Attackers can upload highly compressed files that expand to tens of gigabytes in memory and disk, exhausting server resources and crashing the instance.
CWE

Title
Vikunja before 2.6.0 Denial of Service via Avatar Upload
Summary
Vikunja before 2.6.0 fails to apply pixel decode limits to avatar and project-background upload endpoints, allowing authenticated users to upload crafted images that decode to excessive pixel counts. Attackers can upload small images with extreme aspect ratios that consume significant CPU and memory during processing, causing denial of service through repeated or concurrent uploads.

Mitigation
Architecture and Design

Design throttling mechanisms into the system architecture. The best protection is to limit the amount of resources that an unauthorized user can cause to be expended. A strong authentication and access control model will help prevent such attacks from occurring in the first place. The login application should be protected against DoS attacks as much as possible. Limiting the database access, perhaps by caching result sets, can help minimize the resources expended. To further limit the potential for a DoS attack, consider tracking the rate of requests received from users and blocking requests that exceed a defined rate threshold.

Mitigation
Architecture and Design
  • Mitigation of resource exhaustion attacks requires that the target system either:
  • The first of these solutions is an issue in itself though, since it may allow attackers to prevent the use of the system by a particular valid user. If the attacker impersonates the valid user, they may be able to prevent the user from accessing the server in question.
  • The second solution is simply difficult to effectively institute -- and even when properly done, it does not provide a full solution. It simply makes the attack require more resources on the part of the attacker.
  • recognizes the attack and denies that user further access for a given amount of time, or
  • uniformly throttles all requests in order to make it more difficult to consume resources more quickly than they can again be freed.
Mitigation
Architecture and Design

Ensure that protocols have specific limits of scale placed on them.

Mitigation
Implementation

Ensure that all failures in resource allocation place the system into a safe posture.

CAPEC-147: XML Ping of the Death

An attacker initiates a resource depletion attack where a large number of small XML messages are delivered at a sufficiently rapid rate to cause a denial of service or crash of the target. Transactions such as repetitive SOAP transactions can deplete resources faster than a simple flooding attack because of the additional resources used by the SOAP protocol and the resources necessary to process SOAP messages. The transactions used are immaterial as long as they cause resource utilization on the target. In other words, this is a normal flooding attack augmented by using messages that will require extra processing on the target.

CAPEC-227: Sustained Client Engagement

An adversary attempts to deny legitimate users access to a resource by continually engaging a specific resource in an attempt to keep the resource tied up as long as possible. The adversary's primary goal is not to crash or flood the target, which would alert defenders; rather it is to repeatedly perform actions or abuse algorithmic flaws such that a given resource is tied up and not available to a legitimate user. By carefully crafting a requests that keep the resource engaged through what is seemingly benign requests, legitimate users are limited or completely denied access to the resource.

CAPEC-492: Regular Expression Exponential Blowup

An adversary may execute an attack on a program that uses a poor Regular Expression(Regex) implementation by choosing input that results in an extreme situation for the Regex. A typical extreme situation operates at exponential time compared to the input size. This is due to most implementations using a Nondeterministic Finite Automaton(NFA) state machine to be built by the Regex algorithm since NFA allows backtracking and thus more complex regular expressions.
