{"cve":"CVE-2024-34353","nvd":{"published":"2024-05-14T15:38:43.910","modified":"2026-06-17T07:33:13.997","status":"Deferred","description":"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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","score":5.5},"cwes":["CWE-532"],"references":["https://crates.io/crates/matrix-sdk-crypto/0.7.1","https://github.com/matrix-org/matrix-rust-sdk/commit/71136e44c03c79f80d6d1a2446673bc4d53a2067","https://github.com/matrix-org/matrix-rust-sdk/commit/fa10bbb5dd0f9120a51aa1854cec752e25790bb0","https://github.com/matrix-org/matrix-rust-sdk/releases/tag/matrix-sdk-crypto-0.7.1","https://github.com/matrix-org/matrix-rust-sdk/security/advisories/GHSA-9ggc-845v-gcgv"],"products":[],"source":"nvd","synced_at":"2026-10-19T21:49:23.840078609+00:00"},"epss":{"cve":"CVE-2024-34353","score":0.00193,"percentile":0.09056,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-9ggc-845v-gcgv","url":"https://osv.dev/vulnerability/GHSA-9ggc-845v-gcgv","summary":"matrix-sdk-crypto contains a log exposure of private key of the server-side key backup","modified":"2026-09-10T03:50:13.670354018Z","packages":[{"ecosystem":"crates.io","name":"matrix-sdk-crypto","purl":"pkg:cargo/matrix-sdk-crypto","ranges":[">=0.7.0 <0.7.1"],"fixed":["0.7.1"]}]}],"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).
