It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2025-2866 in the wild and no public exploit code.\n\nAffected product: Libreoffice Libreoffice. 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-2025-2866/ (Markdown: https://insights.sbomify.com/CVE-2025-2866/index.md)","id":"CVE-2025-2866","markdown":"https://insights.sbomify.com/CVE-2025-2866/index.md","name":"CVE-2025-2866","record":{"aliases":["BELL-CVE-2025-2866","DEBIAN-CVE-2025-2866","DSA-5908-1","GHSA-22mj-r7hq-f9h2","MGASA-2025-0154","UBUNTU-CVE-2025-2866","USN-7504-1"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"LibreOffice","requires_auth":"low_privilege","summary":"Attackers can forge PDF signatures in LibreOffice by exploiting improper validation of adbe.pkcs7.sha1 signatures, bypassing integrity checks.","user_interaction":"required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Document Fdn.","cpe":[{"product":"libreoffice","vendor":"libreoffice"}],"cvss":{"score":2.4,"severity":"low","source":"cna","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:P/VC:L/VI:N/VA:N/SC:L/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-347","name":"Improper Verification of Cryptographic Signature"}],"description":"Improper Verification of Cryptographic Signature vulnerability in LibreOffice allows PDF Signature Spoofing by Improper Validation.\n\nIn the affected versions of LibreOffice a flaw in the verification code for adbe.pkcs7.sha1 signatures could cause invalid signatures to be accepted as valid\n\nThis issue affects LibreOffice: from 24.8 before \u003c 24.8.6, from 25.2 before \u003c 25.2.2.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"PDF signature forgery with adbe.pkcs7.sha1 SubFilter","id":"CVE-2025-2866","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"libreoffice:libreoffice","products":["libreoffice:libreoffice"],"type":"security_feature_bypass","year":"2025"},"n_packages":0,"n_references":1,"next":{"headline":"Improper Control of Generation of Code ('Code Injection') in GitLab","id":"CVE-2025-2867"},"packages":[],"prev":{"headline":"Reflected Cross-Site Scripting (XSS) vulnerability in saTECH BCU","id":"CVE-2025-2865"},"products":["LibreOffice"],"published":"2025-04-27","related":[{"cvss_score":10,"headline":"TLS certificate are not properly verified when utilizing LibreOfficeKit","id":"CVE-2024-5261","kev_date_added":null,"published":"2024-06-25"},{"cvss_score":9.8,"headline":"Windows 8.3 path equivalence handling flaw allows LibreLogo script execution","id":"CVE-2019-9855","kev_date_added":null,"published":"2019-09-06"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2018-14939","kev_date_added":null,"published":"2018-08-05"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2017-8358","kev_date_added":null,"published":"2017-04-30"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2017-7882","kev_date_added":null,"published":"2017-04-15"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2016-10327","kev_date_added":null,"published":"2017-04-14"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2017-7856","kev_date_added":null,"published":"2017-04-14"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-11-03","vendors":["The Document Foundation"]},"summary":"Attackers can forge PDF signatures in LibreOffice by exploiting improper validation of adbe.pkcs7.sha1 signatures, bypassing integrity checks.","url":"https://insights.sbomify.com/CVE-2025-2866/"}
