{"id":"CVE-2026-19363","url":"https://www.cyber-defence.io/tools/cve/CVE-2026-19363","generatedAt":"2026-10-28T03:42:26.774Z","title":"A vulnerability was found in lmammino oidc-authorizer up to 0.4.0.","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.","published":"2026-08-09T18:16:43.000Z","lastModified":"2026-10-23T20:10:00.000Z","status":"Deferred","sourceIdentifier":"cna@vuldb.com","cvss":{"version":"4.0","score":5.5,"severity":"MEDIUM","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/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/M"},"cwe":["CWE-200","CWE-532"],"affected":[],"epss":{"score":0.00668,"percentile":0.51702,"date":"2026-10-27","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (0.67%).
