CVE-2026-62995
CVE-2026-62995 affects the Python library joserfc (versions ≤ 1.7.1). The issue: joserfc accepts JWTs with trailing padding (==), which is non-conforming to JOSE specs and enables JWT malleability when parsed by the library. Practical impact varies by deployment and could allow bypass of token re...

CVE-2026-46654 Plonky3 MultiField32Challenger: transcript malleability and challenge entropy loss
Plonky3 is a toolkit for polynomial IOPs PIOPs. Prior to versions 0.4.3 and 0.5.3, an attacker controlling prover-side observations can craft distinct transcripts that produce identical challenges, breaking the binding property of Fiat-Shamir. This issue has been patched in versions 0.4.3 and 0.5...
CVE-2026-46654
The CVE-2026-46654 issue affects Plonky3’s MultiField32Challenger in the prover transcript handling, where transcript malleability allows an attacker controlling prover-side observations to craft transcripts that yield identical challenges, breaking Fiat-Shamir binding. Root cause: a mismatch bet...

On the (Non-)Resilience of Encrypted Controllers to Covert Attacks
The security of networked control systems NCS is receiving increasing attention from both cyber-security and system-theoretic perspectives. The former focuses on classical IT security goals such as confidentiality, integrity, and availability of process data, while the latter investigates tailore...
GHSA-X3FF-W252-2G7J StableLib Ed25519 Signature Malleability via Missing S < L Check
Ed25519 Signature Malleability via Missing S = L to prevent signature malleability. When S = L, SB = S mod LB = S - LB, meaning two different 32-byte S values produce the same verification result. An attacker who observes a valid signature R, S can produce a second valid signature R, S + L for th...
