CVE-2026-53870
Hermes Agent before 0.16.0 creates response_store.db and webhook_subscriptions.json with world-readable permissions (0644), exposing conversation history, tool payloads, prompts, and per-route HMAC secrets to local users. Attackers with local filesystem access can read these files directly to obt...
postgresql: PostgreSQL: Credential recovery via covert timing channel in MD5 password comparison
A flaw was found in PostgreSQL. This vulnerability, a covert timing channel, exists in the comparison of MD5-hashed passwords during authentication. A remote attacker could exploit this to recover user credentials, gaining unauthorized access to the database. This issue specifically impacts...
GHSA-XGMM-8J9V-C9WX PyJWT: Public-key JWK accepted as HMAC secret enables forged HS256 tokens when mixed families are allowed
!NOTE Exploitation requires a verifier configured with both symmetric and asymmetric algorithms in algorithms=… and a raw-JSON JWK as the key= argument, both contrary to documented usage, hence the High attack-complexity rating. Summary When the verifier is decoding JSON Web Tokens, while...
GHSA-RRJ9-5Q2J-4GVR Symfony: Mailomat Mailer Webhook Parser Reads the HMAC Algorithm from the Request: Signature Algorithm Downgrade
Description Symfony\Component\Mailer\Bridge\Mailomat\Webhook\MailomatRequestParser::validateSignature parses the X-MOM-Webhook-Signature request header as algo=signature and passes the wire-supplied $algo directly to hashhmac when verifying the request against the configured webhook secret. The...
GHSA-3Q2P-72CJ-682C File Browser: Improper Access Control Occurs via Pre-Created Public Share for a Non-existent Path
Summary This is similar vulnrability of CVE-2026-0035, which was fixed in Android MediaProvider with high severity. In the original Java issue, MediaStore.createWriteRequest accepted attacker-controlled URIs and created a future grant even when the referenced media item did not exist yet. The...
Insecure Randomness
Overview Affected versions of this package are vulnerable to Insecure Randomness in the form of generating stateless reset-tokens based on HMAC connection ID. An attacker in a MitM position can deduce token material by observing QUIC headers after a source CID rotation, and can cause service...
openssl: PKCS#12 Files with PBMAC1 Are Accepted with Short HMAC Keys
A flaw was found in OpenSSL. This vulnerability allows a remote attacker to forge PKCS12 Public-Key Cryptography Standards 12 files that use Password-Based Message Authentication Code 1 PBMAC1 with short HMAC Hash-based Message Authentication Code keys. This can lead to a service accepting...
USN-8414-1 openssl vulnerabilities
Frank Buss discovered that OpenSSL had a heap buffer over-read in ASN.1 content parsing. An attacker could possibly use this issue to cause OpenSSL to crash, resulting in a denial of service, or obtain sensitive information. CVE-2026-34180 Pavol Zacik and Alex Gaynor discovered that OpenSSL...
Hiding the Trees in the Forest: Building Network Covert Channels with Hash-Based Covert Carrier Filtering
As an effective anti-censorship mechanism, network covert channels can provide data privacy protection and ensure communication security. However, the covertness of existing network covert channels primarily depends on the secrecy of their covert algorithms. With the increasing depth of research ...
CVE-2026-46291
A flaw was found in the Linux kernel's crypto: caam component. This vulnerability allows for the disclosure of sensitive HMAC Hash-based Message Authentication Code key bytes at runtime. The issue occurs because the hashdigestkey function uses printhexdumpdevel without proper guarding, which can...

PT-2026-44930
Name of the Vulnerable Software and Affected Versions liboqs versions prior to 0.16.0 Description An out-of-bounds read exists in the XMSS and XMSS^MT stateful signature verification code. This occurs when the verification function is called with a signature buffer shorter than the expected size...
CVE-2026-45039
RustFS is a distributed object storage system built in Rust. Prior to 1.0.0-beta.2, the internode RPC layer authenticates every request with an HMAC-SHA256 signature using a shared secret. The function that produces this secret, getsharedsecret in crates/ecstore/src/rpc/httpauth.rs, falls back to...
CVE-2026-45039 RustFS: Internode RPC HMAC secret falls back to public default credential, enabling peer impersonation
RustFS is a distributed object storage system built in Rust. Prior to 1.0.0-beta.2, the internode RPC layer authenticates every request with an HMAC-SHA256 signature using a shared secret. The function that produces this secret, getsharedsecret in crates/ecstore/src/rpc/httpauth.rs, falls back to...
PYSEC-2026-179
PyJWT is a JSON Web Token implementation in Python. Prior to 2.13.0, when the verifier is decoding JSON Web Tokens, while supporting both asymmetric and HMAC algorithms, the library does not validate use of JSON Web Keys in HMAC algorithm, allowing attacker to use the issuer public key as the...
