Title
SH3 Módulo de Gestão/Módulo de Arrecadação weak password hash
Summary
A security vulnerability has been detected in SH3. This affects an unknown function of the component Módulo de Gestão/Módulo de Arrecadação. The manipulation leads to password hash with insufficient computational effort. The attack is possible to be carried out remotely. A high degree of complexity is needed for the attack. The exploitability is reported as difficult. The exploit has been disclosed publicly and may be used. Upgrading to version 2026.0.2.0 mitigates this issue. Upgrading the affected component is recommended.

CVE-2026-114616 (GCVE-0-2026-114616)

Vulnerability from cvelistv5 – Published: 2026-10-22 21:14 – Updated: 2026-10-22 21:14

Title
Authlib accepts an empty HMAC key, allowing JWS/JWT signature forgery (HS256/HS384/HS512)
Summary
Authlib is a Python library which builds OAuth and OpenID Connect servers. Prior to 1.9.1, Authlib's OctKey.import_key() and HMAC signing and verification path accept zero-length key material. If an application's secret lookup can return an empty string or empty bytes, a remote attacker can compute the deterministic HS256, HS384, or HS512 signature for arbitrary token claims and have Authlib treat the token as authentic. This issue is fixed in version 1.9.1.
Severity
7.4 (High)

Title
YzmCMS MD5 system.func.php password weak password hash
Summary
A weakness has been identified in YzmCMS up to 7.6. Impacted is the function Password of the file /common/function/system.func.php of the component MD5 Handler. Executing a manipulation of the argument pass can lead to password hash with insufficient computational effort. The attack may be launched remotely. This attack is characterized by high complexity. The exploitability is considered difficult. The exploit has been made available to the public and could be used for attacks. The vendor kindly explains: "Our regular release cycle is about 6 months. The last release was in the previous month, and our next scheduled version will be released in March 2027. We will implement the backward-compatible gradual hash migration feature in this upcoming release. (...) Before the new version is available, we will publish security mitigation guidance on our official documentation for existing deployers to reduce the risk."

CVE-2026-81718 (GCVE-0-2026-81718)

Title
openssl_encrypt before 1.4.9 Weak Cryptographic Parameters
Summary
openssl_encrypt versions before 1.4.9 use under-parameterized PBKDF2-HMAC-SHA256 with only 100,000 iterations to protect PQC keyfile private keys and 10,000 iterations for dual-encryption file-password verification. Attackers who obtain keyfiles or encrypted files can brute-force wrapping passwords offline using GPU or ASIC acceleration.

Title
RabbitMQ amqp091-go: Missing Explicit TLS Minimum Version Configuration In URI Parser
Summary
RabbitMQ amqp091-go is a Go AMQP 0.9.1 client. Prior to 1.13.0, tlsConfigFromURI in uri.go creates tls.Config values without setting MinVersion to tls.VersionTLS12. Builds using a Go runtime whose default permits TLS 1.0 or TLS 1.1 can therefore negotiate an obsolete protocol version when connecting through an amqps URI. A network attacker able to influence TLS negotiation with such a legacy build may weaken transport protection for AMQP messages and credentials. This issue is fixed in version 1.13.0.

9.4 (Critical)

CVE-2026-74889 (GCVE-0-2026-74889)

Vulnerability from cvelistv5 – Published: 2026-08-17 11:04 – Updated: 2026-10-01 15:20

Title
openssl_encrypt before 1.4.0 Weak Key Derivation via HKDF
Summary
openssl_encrypt versions before 1.4.0 use HKDF with no salt and static info parameter in key normalization functions, reducing entropy extraction and determinism. Attackers can exploit predictable key derivation with identical inputs to weaken cryptographic security against multi-target attacks.

Mitigation
Architecture and Design

Use an encryption scheme that is currently considered to be strong by experts in the field.

CAPEC-112: Brute Force

In this attack, some asset (information, functionality, identity, etc.) is protected by a finite secret value. The attacker attempts to gain access to this asset by using trial-and-error to exhaustively explore all the possible secret values in the hope of finding the secret (or a value that is functionally equivalent) that will unlock the asset.

CAPEC-192: Protocol Analysis

An adversary engages in activities to decipher and/or decode protocol information for a network or application communication protocol used for transmitting information between interconnected nodes or systems on a packet-switched data network. While this type of analysis involves the analysis of a networking protocol inherently, it does not require the presence of an actual or physical network.

CAPEC-20: Encryption Brute Forcing

An attacker, armed with the cipher text and the encryption algorithm used, performs an exhaustive (brute force) search on the key space to determine the key that decrypts the cipher text to obtain the plaintext.
