{“lastseen”:””,”description”:”Parsec is a cloud-based application for cryptographically secure file sharing. In versions on the 3.x branch prior to 3.6.0, `libparsec_crypto`, a component of the Parsec application, does not check for weak order point of Curve25519 when compiled with its RustCrypto backend. In practice this means an attacker in a man-in-the-middle position would be able to provide weak order points to both parties in the Diffie-Hellman exchange, resulting in a high probability to for both parties to obtain the same shared key (hence leading to a successful SAS code exchange, misleading both parties into thinking no MITM has occurred) which is also known by the attacker. Note only Parsec web is impacted (as Parsec desktop uses `libparsec_crypto` with the libsodium backend). Version 3.6.0 of Parsec patches the issue.”,”published”:”2026-01-29T15:46:50.922Z”,”modified”:”2026-01-29T15:46:50.922Z”,”type”:”cve”,”title”:”`libparsec_crypto` does not check for weak order point of curve 25519″,”source”:”GitHub_M”,”references”:”https:\/\/github.com\/Scille\/parsec-cloud\/security\/advisories\/GHSA-hrc9-gm58-pgj9\\nhttps:\/\/github.com\/Scille\/parsec-cloud\/commit\/197bb6387b49fec872b5e4a04dcdb82b3d2995b2\\nhttps:\/\/github.com\/Scille\/parsec-cloud\/blob\/e7c5cdbc4234f606ccf3ab2be7e9edc22db16feb\/libparsec\/crates\/crypto\/src\/rustcrypto\/private.rs#L136-L138\\nhttps:\/\/github.com\/dalek-cryptography\/curve25519-dalek\/blob\/8c53a8f10b146a2fd65069437e3576e49b390e7a\/curve25519-dalek\/src\/montgomery.rs#L132-L146\\nhttps:\/\/github.com\/dalek-cryptography\/curve25519-dalek\/blob\/8c53a8f10b146a2fd65069437e3576e49b390e7a\/x25519-dalek\/src\/x25519.rs#L364-L366″,”id”:”CVE-2025-62514″,”bulletinFamily”:””,”cwe”:[“CWE-327″,”CWE-1240″],”cvelist”:null,”sourceData”:”Scille parsec-cloud \\u003e= 3.0.0-alpha, \\u003c 3.6.0″,”sourceHref”:””,”cvss”:{“score”:8.3,”severity”:”HIGH”,”vector”:”CVSS:3.1\/AV:N\/AC:L\/PR:L\/UI:N\/S:U\/C:H\/I:H\/A:L”,”version”:”3.1″},”cvss2″:{},”cvss3″:{“version”:””,”vectorString”:””,”baseScore”:0,”baseSeverity”:””,”attackVector”:””,”attackComplexity”:””,”privilegesRequired”:””,”userInteraction”:””,”scope”:””,”confidentialityImpact”:””,”integrityImpact”:””,”availabilityImpact”:””,”cvssV3″:{“version”:””,”vectorString”:””,”baseScore”:0,”baseSeverity”:””,”attackVector”:””,”attackComplexity”:””,”privilegesRequired”:””,”userInteraction”:””,”scope”:””,”confidentialityImpact”:””,”integrityImpact”:””,”availabilityImpact”:””}},”href”:””,”category_name”:”CVE”,”post_link”:””,”product”:”parsec-cloud”,”version”:”\\u003e= 3.0.0-alpha, \\u003c 3.6.0″,”vendor”:”Scille”,”ai_description”:””,”ai_severity”:””,”ai_vendor”:””,”ai_product”:””,”ai_version”:””,”ai_score”:0}<\/p>\n","protected":false},"excerpt":{"rendered":"
