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."}],"metrics":[{"cvssV4_0":{"version":"4.0","baseScore":6.9,"vectorString":"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","baseSeverity":"MEDIUM"}},{"cvssV3_1":{"version":"3.1","baseScore":5.3,"vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N/E:P/RL:X/RC:R","baseSeverity":"MEDIUM"}},{"cvssV3_0":{"version":"3.0","baseScore":5.3,"vectorString":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N/E:P/RL:X/RC:R","baseSeverity":"MEDIUM"}},{"cvssV2_0":{"version":"2.0","baseScore":5,"vectorString":"AV:N/AC:L/Au:N/C:P/I:N/A:N/E:POC/RL:ND/RC:UR"}}],"timeline":[{"time":"2026-08-08T00:00:00.000Z","lang":"en","value":"Advisory disclosed"},{"time":"2026-08-08T02:00:00.000Z","lang":"en","value":"VulDB entry created"},{"time":"2026-08-10T11:53:26.000Z","lang":"en","value":"VulDB entry last update"}],"credits":[{"lang":"en","value":"changli (VulDB User)","type":"reporter"},{"lang":"en","value":"changli (VulDB User)","type":"analyst"},{"lang":"en","value":"VulDB CNA Team","type":"coordinator"}],"references":[{"url":"https://vuldb.com/vuln/387217","name":"VDB-387217 | lmammino oidc-authorizer Lambda Authorizer handler.rs log file","tags":["vdb-entry"]},{"url":"https://vuldb.com/vuln/387217/cti","name":"VDB-387217 | CTI Indicators (IOB, IOC, TTP, IOA)","tags":["signature","permissions-required"]},{"url":"https://vuldb.com/cve/CVE-2026-19363","name":"CVE-2026-19363 | CVE Analysis and Report","tags":["third-party-advisory"]},{"url":"https://vuldb.com/submit/866093","name":"Submit #866093 | lmammino oidc-authorizer 0.4.0 Exposure of Sensitive Information Through Metadata","tags":["third-party-advisory"]}],"x_generator":["VulDB PVTS v202608"]},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-08-11T01:48:34.120395Z","id":"CVE-2026-19363","options":[{"Exploitation":"none"},{"Automatable":"no"},{"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":"2026-08-11T01:48:52.014Z"}}]}}
