The "tarfile" module would still apply normalization of AREGTYPE \x00 blocks to DIRTYPE, even while processing a multi-block member such as GNUTYPELONGNAME or GNUTYPELONGLINK. This could result in a crafted tar archive being misinterpreted by the tarfile module compared to other implementations...

CVE-2025-13462

CVE-2025-13462 concerns the Python tarfile module: it would normalize AREGTYPE (\x00) blocks to DIRTYPE even when processing GNU LONGNAME/LONGLINK multiblock members, which could cause a crafted tar archive to be interpreted differently from other implementations. Affected stack/impact are descri...

GHSA-2CJM-2GWV-M892 Parse Server's OAuth2 adapter shares mutable state across providers via singleton instance

Impact Parse Server's built-in OAuth2 auth adapter exports a singleton instance that is reused directly across all OAuth2 provider configurations. Under concurrent authentication requests for different OAuth2 providers, one provider's token validation may execute using another provider's...

SUSE CVE-2026-31838

Istio is an open platform to connect, manage, and secure microservices. Prior to 1.29.1, 1.28.5, and 1.27.8, a vulnerability in Envoy RBAC header matching could allow authorization policy bypass when policies rely on HTTP headers that may contain multiple values. An attacker could craft requests...

BIT-ENVOY-2026-26308 Envoy has an RBAC Header Validation Bypass via Multi-Value Header Concatenation

Envoy is a high-performance edge/middle/service proxy. Prior to 1.37.1, 1.36.5, 1.35.8, and 1.34.13, the Envoy RBAC Role-Based Access Control filter contains a logic vulnerability in how it validates HTTP headers when multiple values are present for the same header name. Instead of validating eac...

ChainFuzzer: Greybox Fuzzing for Workflow-Level Multi-Tool Vulnerabilities in LLM Agents

Tool-augmented LLM agents increasingly rely on multi-step, multi-tool workflows to complete real tasks. This design expands the attack surface, because data produced by one tool can be persisted and later reused as input to another tool, enabling exploitable source-to-sink dataflows that only...

PT-2026-25023

Name of the Vulnerable Software and Affected Versions tarfile module affected versions not specified Description The 'tarfile' module incorrectly normalizes AREGTYPE blocks to DIRTYPE when processing multi-block members like GNUTYPE LONGNAME or GNUTYPE LONGLINK. This can cause crafted tar archive...

Keycloak: Improper Access Control Leading to MFA Deletion and Account Takeover in Keycloak Account REST API

A flaw was identified in the Account REST API of Keycloak that allows a user authenticated at a lower security level to perform sensitive actions intended only for higher-assurance sessions. Specifically, an attacker who has already obtained a victim’s password can delete the victim’s registered...
