{"id":"CURL-CVE-2025-14819","summary":"OpenSSL partial chain store policy bypass","details":"When doing TLS related transfers with reused easy or multi handles and\naltering the `CURLSSLOPT_NO_PARTIALCHAIN` option, libcurl could accidentally\nreuse a CA store cached in memory for which the partial chain option was\nreversed. Contrary to the user's wishes and expectations. This could make\nlibcurl find and accept a trust chain that it otherwise would not.","aliases":["CVE-2025-14819"],"modified":"2026-05-21T06:00:13.700253291Z","published":"2026-01-07T08:00:00Z","database_specific":{"package":"curl","last_affected":"8.17.0","www":"https://curl.se/docs/CVE-2025-14819.html","URL":"https://curl.se/docs/CVE-2025-14819.json","award":{"currency":"USD","amount":"505"},"affects":"lib","severity":"Low","CWE":{"desc":"Improper Certificate Validation","id":"CWE-295"}},"affected":[{"ranges":[{"type":"SEMVER","events":[{"introduced":"7.87.0"},{"fixed":"8.18.0"}]},{"type":"GIT","repo":"https://github.com/curl/curl.git","events":[{"introduced":"3c16697ebd796f799227be293e8689aec5f8190d"},{"fixed":"cd046f6c93b39d673a58c18648d8906e954c4f5d"}]}],"versions":["8.17.0","8.16.0","8.15.0","8.14.1","8.14.0","8.13.0","8.12.1","8.12.0","8.11.1","8.11.0","8.10.1","8.10.0","8.9.1","8.9.0","8.8.0","8.7.1","8.7.0","8.6.0","8.5.0","8.4.0","8.3.0","8.2.1","8.2.0","8.1.2","8.1.1","8.1.0","8.0.1","8.0.0","7.88.1","7.88.0","7.87.0","rc-8_18_0-2","rc-8_18_0-1","curl-8_17_0","curl-8_16_0","curl-8_15_0","curl-8_14_1","curl-8_14_0","curl-8_13_0","curl-8_12_1","curl-8_12_0","curl-8_11_1","curl-8_11_0","curl-8_10_1","curl-8_10_0","curl-8_9_1","curl-8_9_0","curl-8_8_0","curl-8_7_1","curl-8_7_0","curl-8_6_0","curl-8_5_0","tiny-curl-8_4_0","curl-8_4_0","curl-8_3_0","curl-8_2_1","curl-8_2_0","curl-8_1_2","curl-8_1_1","curl-8_1_0","curl-8_0_1","curl-8_0_0","curl-7_88_1","curl-7_88_0","curl-7_87_0"],"database_specific":{"source":"https://curl.se/docs/CURL-CVE-2025-14819.json"}}],"schema_version":"1.7.5","credits":[{"name":"Stanislav Fort (Aisle Research)","type":"FINDER"},{"name":"Daniel Stenberg","type":"REMEDIATION_DEVELOPER"}]}
