A p2c parameter set too high in JWE's algorithm PBES2-* could lead to a denial of service. The JWE key management algorithms based on PBKDF2 require a JOSE Header Parameter called p2c (PBES2 Count). This parameter dictates the number of PBKDF2 iterations needed to derive a CEK wrapping key. Its primary purpose is to intentionally slow down the key derivation function, making password brute-force and dictionary attacks more resource- intensive. Therefore, if an attacker sets the p2c parameter in JWE to a very large number, it can cause a lot of computational consumption, resulting in a denial of service. This vulnerability has been addressed in commit `64f2a229b` which has been included in release version 1.2.27 and 2.0.18. Users are advised to upgrade. There are no known workarounds for this vulnerability."}],"source":{"advisory":"GHSA-7f9x-gw85-8grf","discovery":"UNKNOWN"}},"adp":[{"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2024-08-02T21:53:45.354Z"},"title":"CVE Program Container","references":[{"name":"https://github.com/lestrrat-go/jwx/security/advisories/GHSA-7f9x-gw85-8grf","tags":["x_refsource_CONFIRM","x_transferred"],"url":"https://github.com/lestrrat-go/jwx/security/advisories/GHSA-7f9x-gw85-8grf"},{"name":"https://github.com/lestrrat-go/jwx/commit/64f2a229b8e18605f47361d292b526bdc4aee01c","tags":["x_refsource_MISC","x_transferred"],"url":"https://github.com/lestrrat-go/jwx/commit/64f2a229b8e18605f47361d292b526bdc4aee01c"}]},{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2025-05-29T13:39:14.855916Z","id":"CVE-2023-49290","options":[{"Exploitation":"poc"},{"Automatable":"yes"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2025-05-29T13:39:54.272Z"}}]}}
