{"id":"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":["CURL-CVE-2025-14819"],"modified":"2026-09-18T11:30:52.258409062Z","published":"2026-01-08T10:07:54.408Z","related":["SUSE-SU-2026:0050-1","SUSE-SU-2026:0051-1","SUSE-SU-2026:0052-1","SUSE-SU-2026:0066-1","SUSE-SU-2026:0508-1","SUSE-SU-2026:20042-1","SUSE-SU-2026:20062-1","SUSE-SU-2026:20082-1","SUSE-SU-2026:20110-1","openSUSE-SU-2026:10017-1","openSUSE-SU-2026:20031-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/14xxx/CVE-2025-14819.json","unresolved_ranges":[{"extracted_events":[{"introduced":"7.87.0"},{"fixed":"8.14.2"},{"introduced":"8.15.0"},{"fixed":"8.16.1"},{"introduced":"3c16697ebd796f799227be293e8689aec5f8190d"},{"fixed":"cd046f6c93b39d673a58c18648d8906e954c4f5d"}],"source":"AFFECTED_FIELD"}],"cna_assigner":"curl","cwe_ids":["CWE-295"]},"references":[{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2026/01/07/5"},{"type":"WEB","url":"https://curl.se/docs/CVE-2025-14819.html"},{"type":"WEB","url":"https://curl.se/docs/CVE-2025-14819.json"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/14xxx/CVE-2025-14819.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-14819"},{"type":"PACKAGE","url":"https://github.com/curl/curl.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/curl/curl","events":[{"introduced":"c12fb3ddaf48e709a7a4deaa55ec485e4df163ee"},{"fixed":"2eebc58c4b8d68c98c8344381a9f6df4cca838fd"}],"database_specific":{"extracted_events":[{"introduced":"7.87.0"},{"fixed":"8.18.0"}],"source":"CPE_RANGE","cpe":"cpe:2.3:a:haxx:curl:*:*:*:*:*:*:*:*"}}],"versions":["7.87.0","7.88.0","7.88.1","8.0.0","8.0.1","8.1.0","8.1.1","8.1.2","8.10.0","8.10.1","8.11.0","8.11.1","8.12.0","8.12.1","8.13.0","8.14.0","8.14.1","8.15.0","8.16.0","8.2.0","8.2.1","8.3.0","8.4.0","8.5.0","8.6.0","8.7.0","8.7.1","8.8.0","8.9.0","8.9.1","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","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://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2025-14819.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:N/A:N"}]}
