{"id":"CVE-2024-34353","summary":"matrix-sdk-crypto contains a log exposure of private key of the server-side key backup","details":"The matrix-sdk-crypto crate, part of the Matrix Rust SDK project, is an implementation of a Matrix end-to-end encryption state machine in Rust. In Matrix, the server-side `key backup` stores encrypted copies of Matrix message keys. This facilitates key sharing between a user's devices and provides a redundant copy in case all devices are lost. The key backup uses asymmetric\ncryptography, with each server-side key backup assigned a unique public-private key pair. Due to a logic bug introduced in commit 71136e44c03c79f80d6d1a2446673bc4d53a2067, matrix-sdk-crypto version 0.7.0 will sometimes log the private part of the backup key pair to Rust debug logs (using the `tracing` crate). This issue has been resolved in matrix-sdk-crypto version 0.7.1. No known workarounds are available.","aliases":["GHSA-9ggc-845v-gcgv"],"modified":"2026-11-04T02:46:17.489843497Z","published":"2024-05-13T15:43:10.574Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/34xxx/CVE-2024-34353.json","cna_assigner":"GitHub_M","cwe_ids":["CWE-532"]},"references":[{"type":"WEB","url":"https://crates.io/crates/matrix-sdk-crypto/0.7.1"},{"type":"WEB","url":"https://github.com/matrix-org/matrix-rust-sdk/releases/tag/matrix-sdk-crypto-0.7.1"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/34xxx/CVE-2024-34353.json"},{"type":"ADVISORY","url":"https://github.com/matrix-org/matrix-rust-sdk/security/advisories/GHSA-9ggc-845v-gcgv"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-34353"},{"type":"FIX","url":"https://github.com/matrix-org/matrix-rust-sdk/commit/71136e44c03c79f80d6d1a2446673bc4d53a2067"},{"type":"FIX","url":"https://github.com/matrix-org/matrix-rust-sdk/commit/fa10bbb5dd0f9120a51aa1854cec752e25790bb0"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/matrix-org/matrix-rust-sdk","events":[{"introduced":"4f9e8f0ae58d5a2c3c06e600d60940bc725e4cb4"},{"fixed":"71136e44c03c79f80d6d1a2446673bc4d53a2067"},{"fixed":"fa10bbb5dd0f9120a51aa1854cec752e25790bb0"},{"fixed":"48cf21e37c701cb7318c6518b4d69b3918a5343f"}],"database_specific":{"extracted_events":[{"strategy":"StandaloneSingleVersion","range":[{"introduced":"= 0.7.0"},{"last_affected":"= 0.7.0"}],"source":"AFFECTED_FIELD"},{"source":"REFERENCES_COMMIT","range":[{"fixed":"71136e44c03c79f80d6d1a2446673bc4d53a2067"}]},{"range":[{"fixed":"fa10bbb5dd0f9120a51aa1854cec752e25790bb0"}],"source":"REFERENCES_COMMIT"},{"original_tag":"matrix-sdk-crypto-0.7.1","range":[{"fixed":"48cf21e37c701cb7318c6518b4d69b3918a5343f"}],"source":"REFERENCES_TAG"}]}}],"versions":["= 0.7.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2024-34353.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N"}]}
