  * CVE-2026-62995

CVE-2026-62995 is a security flaw in the joserfc Python library that processes JSON Web Tokens (JWTs). The vulnerability arises from the library's acceptance of JWTs containing non-standard trailing padding, which can be exploited to create malleable tokens. This malleability may allow attackers to circumvent security mechanisms such as token revocation and anti-replay protections in applications relying on joserfc for JWT validation. The vulnerability affects Red Hat Hardened Images RPMs, specifically the jaeger package version 2.20.0-0.8.hum1 for aarch64 and x86_64. Red Hat has published an advisory (RHSA-2026:48758) detailing the issue and the affected packages. While no explicit patch link is provided, the advisory references updated RPMs including the fixed version. Red Hat rates this vulnerability as critical due to its potential impact on authentication security.

Red Hat Security Advisory: Red Hat Hardened Images RPMs Security Update

CVE-2026-27459 is a buffer overflow vulnerability in the pyOpenSSL library affecting the set_cookie_generate_callback function used to generate DTLS cookies. If the custom callback returns a cookie longer than 256 bytes, a buffer overflow occurs due to missing bounds checking before copying data into a fixed-size buffer in OpenSSL. This can lead to memory corruption, potential unauthorized code execution, or denial of service. The vulnerability requires a custom callback returning an excessively long cookie, limiting exposure. Red Hat's advisory rates the severity as important and recommends ensuring the callback limits cookie length to under 256 bytes. The issue is tracked under multiple CWEs including CWE-120 (classic buffer overflow).

joserfc

The joserfc Python library versions 1.7.1 and earlier accept JSON Web Tokens (JWTs) with trailing padding characters (==), which violates JOSE specifications and causes token malleability. This malleability can potentially allow bypassing token revocation or anti-replay protections that rely on deny lists of tokens or token hashes. The issue has been fixed in version 1.7.2.

joserfc, a Python library implementing JOSE standards, in versions up to 1.7.1 accepts JWTs containing trailing padding ('=='), which is non-compliant with JOSE specifications. This acceptance leads to malleability of JWTs, meaning tokens can be altered without invalidating their signature under certain signature schemes. Such malleability may undermine security mechanisms like token revocation or anti-replay protections that depend on the assumption that tokens are immutable. The vulnerability does not affect ECDSA JWS tokens uniquely, as ECDSA signatures are inherently malleable. The issue was addressed and fixed in version 1.7.2.
