Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-45447 in the wild and no public exploit code.\n\nAffected product: Openssl Openssl. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-45447/ (Markdown: https://insights.sbomify.com/CVE-2026-45447/index.md)","id":"CVE-2026-45447","markdown":"https://insights.sbomify.com/CVE-2026-45447/index.md","name":"CVE-2026-45447","record":{"aliases":["ALPINE-CVE-2026-45447","ALSA-2026:36215","ALSA-2026:44438","AZL-89811","AZL-89864","AZL-92837","BELL-CVE-2026-45447","CLSA-2026-1781175688","CLSA-2026-1781208261","CLSA-2026-1781209013","CLSA-2026-1781209312","CLSA-2026-1781253686","CLSA-2026-1781276539","CLSA-2026-1781343514","CLSA-2026-1781343538","CLSA-2026-1781549039","CLSA-2026-1782152516","CLSA-2026-1785154072","CLSA-2026-1785517004","CLSA-2026-1786005006","CLSA-2026-1786005845","CLSA-2026-1786006093","DEBIAN-CVE-2026-45447","GHSA-f684-cpcq-j565","JLSEC-2026-1145","MINI-cgvf-3w8p-hxpg","MINI-cj84-84rv-hf48","RHSA-2026:36215","RHSA-2026:44438","RLSA-2026:36215","RLSA-2026:44438","ROOT-OS-ALPINE-315-CVE-2026-45447","ROOT-OS-ALPINE-317-CVE-2026-45447","ROOT-OS-UBUNTU-2004-CVE-2026-45447","SUSE-SU-2026:2409-1","SUSE-SU-2026:2410-1","SUSE-SU-2026:2412-1","SUSE-SU-2026:2621-1","UBUNTU-CVE-2026-45447"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"OpenSSL cryptographic library","requires_auth":"low_privilege","summary":"A crafted PKCS#7 message triggers a use-after-free in OpenSSL, potentially allowing remote code execution or crashes in applications processing signed messages.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"openssl","cpe":[{"product":"openssl","vendor":"openssl"}],"cvss":{"score":8.8,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-825","name":"Expired Pointer Dereference"},{"id":"CWE-416","name":"Use After Free"}],"description":"Issue summary: A specially crafted PKCS#7 or S/MIME signed message could\ntrigger a use-after-free during PKCS#7 signature verification.\n\nImpact summary: A use-after-free may result in process crashes, heap\ncorruption, or potentially remote code execution.\n\nWhen processing a PKCS#7 or S/MIME signed message, if the SignedData\ndigestAlgorithms field is present as an empty ASN.1 SET, OpenSSL may\nincorrectly free a caller-owned BIO during PKCS7_verify(). A subsequent\nuse of the BIO by the calling application results in a use-after-free\ncondition.\n\nIn the common case this occurs when the application later calls\nBIO_free() on the BIO originally passed to PKCS7_verify(). Depending\non allocator behavior and application-specific BIO usage patterns, this\nmay result in a crash or other memory corruption. In some application\ncontexts this may potentially be exploitable for remote code execution.\n\nApplications that process PKCS#7 or S/MIME signed messages using OpenSSL\nPKCS#7 APIs may be affected. Applications using the CMS APIs for this\nprocessing are not affected.\n\nThe FIPS modules in 4.0, 3.6, 3.5, 3.4, and 3.0 are not affected by this\nissue, as the affected code is outside the OpenSSL
