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-2020-12112/ (Markdown: https://insights.sbomify.com/CVE-2020-12112/index.md)","id":"CVE-2020-12112","markdown":"https://insights.sbomify.com/CVE-2020-12112/index.md","name":"CVE-2020-12112","record":{"aliases":["GHSA-wvwr-5mqr-9r9p"],"analysis":null,"analysis_generated_by":null,"assigner":"mitre","cpe":[{"product":"bigbluebutton","vendor":"bigbluebutton"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"BigBlueButton before 2.2.5 allows remote attackers to obtain sensitive files via Local File Inclusion.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2020-04-23","github_poc":1,"max_poc_stars":14,"metasploit":0,"nuclei":0,"refs":[{"date":"2020-04-23T18:50:23Z","kind":"github_poc","ref":"https://github.com/tchenu/CVE-2020-12112","stars":14,"title":"BigBlueButton versions lower than 2.2.4 have a LFI vulnerability allowing access to sensitive files. 🚨"}],"tier":"poc_unverified"},"has_fix":false,"headline":"BigBlueButton before 2.2.5 allows remote attackers to obtain sensitive files via Local File Inclusion.","id":"CVE-2020-12112","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":null,"year":"2020"},"n_packages":0,"n_references":5,"next":{"headline":"Cross-site scripting in n/a","id":"CVE-2020-12113"},"packages":[],"prev":{"headline":"Command injection in n/a","id":"CVE-2020-12111"},"products":["n/a"],"published":"2020-04-23","related":[{"cvss_score":9.8,"headline":"Other in n/a","id":"CVE-2020-27602","kev_date_added":null,"published":"2020-10-21"},{"cvss_score":9.8,"headline":"Code injection in n/a","id":"CVE-2020-27605","kev_date_added":null,"published":"2020-10-21"},{"cvss_score":9.8,"headline":"Path traversal in n/a","id":"CVE-2020-12443","kev_date_added":null,"published":"2020-04-29"},{"cvss_score":8.4,"headline":"Hardcoded credentials in n/a","id":"CVE-2020-27613","kev_date_added":null,"published":"2020-10-21"},{"cvss_score":8.1,"headline":"Cross-site Scripting (XSS) - Generic in bigbluebutton/bigbluebutton","id":"CVE-2021-4143","kev_date_added":null,"published":"2022-01-19"},{"cvss_score":7.5,"headline":"BigBlueButton vulnerable to DoS via PollSubmitVote GraphQL mutation","id":"CVE-2025-61601","kev_date_added":null,"published":"2025-10-09"},{"cvss_score":7.5,"headline":"BigBlueButton vulnerable to Chat DoS via invalid reactionEmojiId","id":"CVE-2025-61602","kev_date_added":null,"published":"2025-10-09"}],"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)"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["n/a"]},"summary":null,"url":"https://insights.sbomify.com/CVE-2020-12112/"}
