An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2021-20831 in the wild and no public exploit code.\n\nAffected product: Mario Valney OG Tags. 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-2021-20831/ (Markdown: https://insights.sbomify.com/CVE-2021-20831/index.md)","id":"CVE-2021-20831","markdown":"https://insights.sbomify.com/CVE-2021-20831/index.md","name":"CVE-2021-20831","record":{"aliases":["GHSA-w35x-3cc7-37pc"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["account_takeover","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"OG Tags plugin","requires_auth":"none","summary":"A CSRF vulnerability in the OG Tags plugin allows attackers to hijack administrator sessions and perform unintended actions.","user_interaction":"required","vuln_class":"csrf"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jpcert","cpe":[{"product":"og_tags","vendor":"og_tags_project"}],"cvss":{"score":8.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-352","name":"Cross-Site Request Forgery"}],"description":"Cross-site request forgery (CSRF) vulnerability in OG Tags versions prior to 2.0.2 allows a remote attacker to hijack the authentication of administrators and unintended operation may be performed via unspecified vectors.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Cross-site request forgery in OG Tags","id":"CVE-2021-20831","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"csrf","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"Information disclosure in InBody App for iOS versions prior to 2.3.30 and InBody App for Android versions prior to 2.2.90(510)","id":"CVE-2021-20832"},"packages":[],"prev":{"headline":"Cross-site scripting in GROWI","id":"CVE-2021-20829"},"products":["OG Tags"],"published":"2021-10-13","related":[],"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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-03","vendors":["Mario Valney"]},"summary":"A CSRF vulnerability in the OG Tags plugin allows attackers to hijack administrator sessions and perform unintended actions.","url":"https://insights.sbomify.com/CVE-2021-20831/"}
