Prior to version 1.5.6, an attacker can cause a denial of service attack by passing in a malicious JWE Token with a high compression ratio. When the server processes this token, it will consume a lot of memory and processing time. Version 1.5.6 fixes this vulnerability by limiting the maximum token length.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:N/I:N/A:H","score":6.8},"cwes":["CWE-770"],"references":["https://github.com/latchset/jwcrypto/commit/90477a3b6e73da69740e00b8161f53fea19b831f","https://github.com/latchset/jwcrypto/security/advisories/GHSA-j857-7rvv-vj97","https://github.com/latchset/jwcrypto/commit/90477a3b6e73da69740e00b8161f53fea19b831f","https://github.com/latchset/jwcrypto/security/advisories/GHSA-j857-7rvv-vj97","https://lists.debian.org/debian-lts-announce/2024/09/msg00026.html"],"products":["debian:debian_linux","latchset:jwcrypto"],"source":"nvd","synced_at":"2026-10-19T21:47:51.568503435+00:00"},"epss":{"cve":"CVE-2024-28102","score":0.0098,"percentile":0.62239,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-j857-7rvv-vj97","url":"https://osv.dev/vulnerability/GHSA-j857-7rvv-vj97","summary":"JWCrypto vulnerable to JWT bomb Attack in `deserialize` function","modified":"2026-09-10T03:50:10.546310463Z","packages":[{"ecosystem":"PyPI","name":"jwcrypto","purl":"pkg:pypi/jwcrypto","ranges":["<1.5.6"],"fixed":["1.5.6"]}]},{"id":"PYSEC-2026-1484","url":"https://osv.dev/vulnerability/PYSEC-2026-1484","summary":"JWCrypto vulnerable to JWT bomb Attack in `deserialize` function","modified":"2026-07-07T17:47:27.855878776Z","packages":[{"ecosystem":"PyPI","name":"jwcrypto","purl":"pkg:pypi/jwcrypto","ranges":["<1.5.6"],"fixed":["1.5.6"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
