SumatraPDF versions 3.5.0 to 3.5.2 disable TLS hostname verification during update checks using INTERNETFLAGIGNORECERTCNINVALID and do not perform any signature or integrity validation on the downloaded installer. Exploit Title: SumatraPDF 3.5.2 - Remote Code Execution Date: 2026-02-10 Exploit...

The Infinite Mutation Engine? Measuring Polymorphism in LLM-Generated Offensive Code

Malware authors have traditionally relied on polymorphic techniques to produce variants in the same malware family, complicating signature-based detection. Integrating generative AI into offensive toolchains enables attackers to synthesize structurally diverse payloads with identical behavior,...

CoreDNS 安全漏洞

CoreDNS is a DNS server within the CoreDNS community. Versions of CoreDNS prior to 1.14.3 contained a security vulnerability. This vulnerability stemmed from the tsig plugin’s trust transfer writer, which relied on TsigStatus for verification instead of performing its own validation. This allowed...

Linux Distros Unpatched Vulnerability : CVE-2026-7689

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - A security flaw has been discovered in Dolibarr ERP CRM up to 23.0.2. This vulnerability affects the function dolverifyHash in the library...

GHSA-HCWR-PQ9G-RQ3M apko doesn't verify downloaded apk packages against APKINDEX checksum (package substitution possible)

apko verifies the signature on APKINDEX.tar.gz but never compares individually downloaded .apk packages against the checksum recorded in the signed index. The checksum is parsed and available via ChecksumString, and the downloaded package control hash is computed, but the two values are never...

CVE-2026-7689

A security flaw has been discovered in Dolibarr ERP CRM up to 23.0.2. This vulnerability affects the function dolverifyHash in the library htdocs/core/lib/security.lib.php of the component Online Signature Module. The manipulation results in improper verification of cryptographic signature. The...

cryptography: cryptography Subgroup Attack Due to Missing Subgroup Validation for SECT Curves

A validation flaw has been discovered in the python cryptography package. This missing validation allows an attacker to provide a public key point P from a small-order subgroup. This can lead to security issues in various situations, such as the most commonly used signature verification ECDSA and...

Summary Potential vulnerability in auth0/node-jws has been identified that affects IBM watsonx Assistant Cartridge and IBM watsonx Orchestrate with watsonx Assistant Cartridge - Assistant Builder Component. . The vulnerability have been addressed. Refer to details for additional information...

pyjwt: PyJWT accepts unknown `crit` header extensions (RFC 7515 §4.1.11 MUST violation)

A missing verification step has been discovered in PyJWT. PyJWT does not validate the crit Critical Header Parameter defined in RFC 7515 §4.1.11. When a JWS token contains a crit array listing extensions that PyJWT does not understand, the library accepts the token instead of rejecting it. This...

Security Bulletin: cryptography Missing Subgroup Validation in EC Public Keys Enables ECDH Key Leakage and ECDSA Forgery

Summary cryptography is a package designed to expose cryptographic primitives and recipes to Python developers. Prior to 46.0.5, the publickeyfromnumbers or EllipticCurvePublicNumbers.publickey, EllipticCurvePublicNumbers.publickey, loadderpublickey and loadpempublickey functions do not verify th...

OpenSSH: OpenSSH: Information disclosure due to unintended cryptographic algorithm usage

A flaw was found in OpenSSH. This vulnerability allows the system to use unintended Elliptic Curve Digital Signature Algorithm ECDSA algorithms. This occurs because the configuration for accepted public key algorithms is misinterpreted, leading to the use of weaker cryptographic methods than...
