CVE-2026-107724 fast-jwt treats raw public JWK JSON as an HMAC secret, enabling HS256 token forgery

fast-jwt provides fast JSON Web Token JWT implementation. In 6.2.4, fast-jwt can classify raw serialized public JWK or JWKS JSON as an HMAC secret because src/crypto.js performDetectPublicKeyAlgorithms treats non-PEM strings as symmetric key material. If HS256 is explicitly allowed or inferred, a...

CVE-2026-107724

The fast-jwt library (version 6.2.4 ) contains a vulnerability where raw serialized public JWK or JWKS JSON can be incorrectly classified as an HMAC secret . The root cause is located in src/crypto.js within the performDetectPublicKeyAlgorithms function, which treats non-PEM strings as symmetric ...

CVE-2026-107723 fast-jwt : Silent claim-validator bypass when JWT payload is a JSON array

fast-jwt provides fast JSON Web Token JWT implementation. Prior to 6.3.0, fast-jwt createVerifier accepts a validly signed JWT whose payload is a JSON array because src/decoder.js checks that the payload is an object but does not reject arrays. The claim validator loop then finds no named exp, nb...

CVE-2026-107723

The fast-jwt library (versions prior to 6.3.0 ) is vulnerable to a silent claim-validator bypass when a JWT payload is a JSON array . The root cause is located in src/decoder.js, where the system verifies that the payload is an object but fails to reject arrays. Because the claim validator loop l...

CVE-2026-107717 Banks: User-controlled prompt input can be parsed as privileged chat messages

Banks generates meaningful LLM prompts using a simple template language. Prior to 2.5.0, Banks Prompt.chatmessages attempts to parse every line of rendered template output as ChatMessage JSON. When an application renders untrusted data and passes the returned ChatMessage objects to an LLM provide...

DEBIAN-CVE-2026-106438

An incorrect calculation in Decimal128 string parsing in the MongoDB C Driver can accept certain over-precision inputs containing leading zeros instead of rejecting them. This produces a value different from the supplied text. An actor who can provide a decimal string to an embedding application,...

CVE-2026-106438

The MongoDB C Driver contains a vulnerability in its Decimal128 string parsing logic. An incorrect calculation during exactness checks allows the driver to accept certain over-precision inputs containing leading zeros rather than rejecting them. This results in the creation of a numeric value tha...

Coraza: Unbounded recursion in JSON response body processor causes CPU exhaustion

Summary The JSON response body processor parses response bodies with no recursion limit. ProcessResponse calls readJSONss, ignoreJSONRecursionLimit, and that constant is -1. The guard in readItems only fires on == 0, so counting down from -1 -2, -3, ... never reaches it. The guard is effectively...

GHSA-5GJ4-9GM7-2FX2 Coraza body processor has a JSON key collision that allows unauthenticated attackers to bypass OWASP CRS inspection

Summary Coraza's JSON body processor converts nested JSON properties into dot-separated ARGSPOST names without escaping dots contained in literal property names. Two distinct JSON properties can therefore collapse into the same Coraza variable An unauthenticated attacker can place a malicious val...
