Prior to version 0.4.13, the package's use of `flate.NewReader` does not limit the size of the input. The user can pass more than 1 MB of data in the HTTP request to the processing functions, which will be decompressed server-side using the Deflate algorithm. Therefore, after repeating the same request multiple times, it is possible to achieve a reliable crash since the operating system kills the process. This issue is patched in version 0.4.13.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5},"cwes":["CWE-770"],"references":["https://github.com/crewjam/saml/commit/8e9236867d176ad6338c870a84e2039aef8a5021","https://github.com/crewjam/saml/security/advisories/GHSA-5mqj-xc49-246p","https://github.com/crewjam/saml/commit/8e9236867d176ad6338c870a84e2039aef8a5021","https://github.com/crewjam/saml/security/advisories/GHSA-5mqj-xc49-246p"],"products":["saml_project:saml"],"source":"nvd","synced_at":"2026-10-19T21:37:48.383111019+00:00"},"epss":{"cve":"CVE-2023-28119","score":0.00957,"percentile":0.61468,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-5mqj-xc49-246p","url":"https://osv.dev/vulnerability/GHSA-5mqj-xc49-246p","summary":"crewjam/saml vulnerable to Denial Of Service Via Deflate Decompression Bomb","modified":"2026-08-07T08:12:04.985969571Z","packages":[{"ecosystem":"Go","name":"github.com/crewjam/saml","purl":"pkg:golang/github.com/crewjam/saml","ranges":["<0.4.13"],"fixed":["0.4.13"]}]},{"id":"GO-2023-1664","url":"https://osv.dev/vulnerability/GO-2023-1664","summary":"Denial of service via deflate compression bomb in github.com/crewjam/saml","modified":"2026-08-07T08:12:30.812086276Z","packages":[{"ecosystem":"Go","name":"github.com/crewjam/saml","purl":"pkg:golang/github.com/crewjam/saml","ranges":["<0.4.13"],"fixed":["0.4.13"]}]}],"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).
