jose4j: jose4j: Denial of Service via malicious JSON Web Encryption (JWE) token compression

A flaw was found in jose4j. A remote attacker can exploit this by crafting a malicious JSON Web Encryption JWE token with an exceptionally high compression ratio. When this token is processed by the server, it results in significant memory allocation and processing time during decompression. This...

ajv: ReDoS via $data reference

A flaw was found in ajv. When the $data option is enabled, the value of the pattern keyword is passed directly to the JavaScript RegExp constructor without sufficient validation. An attacker able to supply a malicious regular expression pattern can trigger a ReDoS Regular Expression Denial of...
