gnutls: gnutls: Authentication Bypass via NUL Character in Username
A flaw was found in gnutls. Servers configured with RSA-PSK Rivest–Shamir–Adleman – Pre-Shared Key wrongfully matched usernames containing a NUL character with truncated usernames. A remote attacker could exploit this by sending a specially crafted username, leading to an authentication bypass...
CVE-2026-46654
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...
Plonky3 数据伪造问题漏洞
Plonky3 is an open-source implementation of the Polynomial IOP cryptographic primitive toolkit by Plonky3 developers. Versions of Plonky3 prior to 0.4.3 and 0.5.3 contained a data forgery vulnerability. This vulnerability allowed attackers to control the observations made by the prover, resulting...

CVE-2025-59484 AutomationDirect CLICK PLUS Use of a Broken or Risky Cryptographic Algorithm
The use of a broken or risky cryptographic algorithm was discovered in firmware version 3.60 of the Click Plus PLC. The vulnerability relies on the fact that the software uses an insecure implementation of the RSA encryption algorithm...
New Cryptanalysis of the Fiat-Shamir Protocol
A couple of months ago, a new paper demonstrated some new attacks against the Fiat-Shamir transformation. Quanta published a good article that explains the results. This is a pretty exciting paper from a theoretical perspective, but I don't see it leading to any practical real-world cryptanalysis...
CVE-2022-29566
The Bulletproofs 2017/1066 paper mishandles Fiat-Shamir generation because the hash computation fails to include all of the public values from the Zero Knowledge proof statement as well as all of the public values computed in the proof, aka the Frozen Heart issue...
Post Quantum Cryptography (PQC) Signatures without Trapdoors
Some of our current public key methods use a trap door to implement digital signature methods. This includes the RSA method, which uses Fermat's little theorem to support the creation and verification of a digital signature. The problem with a back-door is that the actual trap-door method could, ...
SP1 has missing verifier checks and fiat-shamir observations
In SP1’s STARK verifier, the prover provided chipordering is used to fetch the index of the chips that have preprocessed columns. Prior to v4.0.0, the validation that this chipordering correctly provides these indexes was missing. In v4.0.0, this was fixed by adding a check that the indexed chip’...
