{"id":"CVE-2026-19363","state":"PUBLISHED","title":"lmammino oidc-authorizer Lambda Authorizer handler.rs log file","description":"A vulnerability was found in lmammino oidc-authorizer up to 0.4.0. Impacted is an unknown function of the file src/handler.rs of the component Lambda Authorizer. The manipulation results in sensitive information in log files. The attack can be executed remotely. `src/handler.rs` logs raw Authorization header values and complete bearer tokens/JWTs on authentication failure paths, potentially exposing credentials through CloudWatch Logs. `src/models.rs` serializes the complete validated JWT claims set with `serde_json::to_string(token_claims).unwrap()` and propagates it through `context[\"jwtClaims\"]` to downstream integrations. This code performs serialization, not deserialization, and does not process attacker-controlled `jwtClaims` input. The exploit has been made public and could be used. The vendor was contacted early about this disclosure but did not respond in any way.","publishedAt":"2026-08-09T17:45:07.380Z","updatedAt":"2026-08-11T01:48:52.014Z","severity":{"score":6.9,"label":"Medium","version":"4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:P","source":"VulDB"},"assigner":"VulDB","products":["lmammino oidc-authorizer"],"affected":[{"vendor":"lmammino","product":"oidc-authorizer","versions":[{"version":"0.1","status":"affected"},{"version":"0.2","status":"affected"},{"version":"0.3","status":"affected"},{"version":"0.4.0","status":"affected"}],"cpes":["cpe:2.3:a:lmammino:oidc-authorizer:*:*:*:*:*:*:*:*"],"modules":["Lambda Authorizer"]}],"references":["https://vuldb.com/vuln/387217","https://vuldb.com/vuln/387217/cti","https://vuldb.com/cve/CVE-2026-19363","https://vuldb.com/submit/866093"],"weaknesses":["CWE-532","CWE-200"],"ingestedAt":"2026-10-29T20:11:10.572Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/19xxx/CVE-2026-19363.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-19363","state":"PUBLISHED","datePublished":"2026-08-09T17:45:07.380Z","dateUpdated":"2026-08-11T01:48:52.014Z","assignerShortName":"VulDB","assignerOrgId":"1af790b2-7ee1-4545-860a-a788eba489b5","dateReserved":"2026-08-08T20:18:38.032Z"},"containers":{"cna":{"title":"lmammino oidc-authorizer Lambda Authorizer handler.rs log file","descriptions":[{"lang":"en","value":"A vulnerability was found in lmammino oidc-authorizer up to 0.4.0.
