Such an object has empty signerInfos, so the underlying signed-data verification succeeds without authenticating any content. The compatibility-layer verify path now rejects the object when no signer signature has actually been verified, so a PKCS#7 carrying no valid signature is no longer reported as verified. This is enforced regardless of the `PKCS7_NOVERIFY` flag, which only suppresses signer certificate chain validation and was never intended to waive the requirement that a signature exist. Only affects OpenSSL compatibility builds that call the `PKCS7_verify()` compatibility API on potentially degenerate PKCS#7 bundles.","modified":"2026-07-25T18:24:50.636834028Z","published":"2026-07-14T21:41:35.775Z","upstream":["CVE-2026-55961","GHSA-cj56-5c53-9qjf","EUVD-2026-39491"],"database_specific":{"license":"CC-BY-4.0","sources":[{"html_url":"https://nvd.nist.gov/vuln/detail/CVE-2026-55961","database_specific":{"status":"Analyzed"},"id":"CVE-2026-55961","imported":"2026-07-17T22:33:23.057Z","modified":"2026-06-26T16:50:36.543Z","published":"2026-06-25T18:16:41.213Z","url":"https://services.nvd.nist.gov/rest/json/cves/2.0?cveId=CVE-2026-55961"},{"imported":"2026-07-17T22:33:23.238Z","modified":"2026-06-26T18:33:49Z","published":"2026-06-25T18:30:41Z","url":"https://api.github.com/advisories/GHSA-cj56-5c53-9qjf","html_url":"https://github.com/advisories/GHSA-cj56-5c53-9qjf","id":"GHSA-cj56-5c53-9qjf"},{"url":"https://euvdservices.enisa.europa.eu/api/enisaid?id=EUVD-2026-39491","html_url":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-39491","id":"EUVD-2026-39491","imported":"2026-07-17T22:33:33.026Z","modified":"2026-06-25T17:57:46Z","published":"2026-06-25T16:51:18Z"}]},"references":[{"type":"WEB","url":"https://github.com/advisories/GHSA-cj56-5c53-9qjf"},{"type":"WEB","url":"https://github.com/wolfSSL/wolfssl/pull/10702"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-55961"},{"type":"WEB","url":"https://www.wolfssl.com/docs/security-vulnerabilities"},{"type":"WEB","url":"https://www.wolfssl.com/docs/security-vulnerabilities/"}],"affected":[{"package":{"name":"wolfSSL_jll","ecosystem":"Julia","purl":"pkg:julia/wolfSSL_jll?uuid=98c43586-9870-5ae5-ab22-acc77b9bbdb5"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"5.9.2+0"}]}],"database_specific":{"source":"https://github.com/JuliaLang/SecurityAdvisories.jl/tree/generated/osv/2026/JLSEC-2026-736.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N"},{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X"}]}
