Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-32763 in the wild and no public exploit code.\n\nAffected product: opf openproject. 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-2021-32763/ (Markdown: https://insights.sbomify.com/CVE-2021-32763/index.md)","id":"CVE-2021-32763","markdown":"https://insights.sbomify.com/CVE-2021-32763/index.md","name":"CVE-2021-32763","record":{"aliases":["GHSA-qqvp-j6gm-q56f"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"OpenProject project management","requires_auth":"low_privilege","summary":"An attacker can cause a denial of service in OpenProject forums by submitting messages with unterminated pre tags that trigger excessive regex backtracking.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"openproject","vendor":"openproject"}],"cvss":{"score":4.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L","version":"3.1"},"cwes":[{"id":"CWE-400","name":"Uncontrolled Resource Consumption"}],"description":"OpenProject is open-source, web-based project management software. In versions prior to 11.3.3, the `MessagesController` class of OpenProject has a `quote` method that implements the logic behind the Quote button in the discussion forums, and it uses a regex to strip `\u003cpre\u003e` tags from the message being quoted. The `(.|\\s)` part can match a space character in two ways, so an unterminated `\u003cpre\u003e` tag containing `n` spaces causes Ruby's regex engine to backtrack to try 2\u003csup\u003en\u003c/sup\u003e states in the NFA. This will result in a Regular Expression Denial of Service. The issue is fixed in OpenProject 11.3.3. As a workaround, one may install the patch manually.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Regular Expression Denial of Service in OpenProject forum messages","id":"CVE-2021-32763","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"YouTube Onebox susceptible to XSS","id":"CVE-2021-32764"},"packages":[],"prev":{"headline":"Integer overflow that can lead to heap overflow in redis-cli, redis-sentinel on some platforms","id":"CVE-2021-32762"},"products":["openproject"],"published":"2021-07-20","related":[{"cvss_score":9.9,"headline":"OpenProject: SQL Injection in Cost Reporting =n Operator via parse_number_string","id":"CVE-2026-34717","kev_date_added":null,"published":"2026-04-02"},{"cvss_score":9.4,"headline":"Command Injection on OpenProject repositories leads to Remote Code Execution","id":"CVE-2026-25763","kev_date_added":null,"published":"2026-02-06"},{"cvss_score":9.4,"headline":"OpenProject has Argument Injection on Repository module that allows Arbitrary File Write","id":"CVE-2026-24685","kev_date_added":null,"published":"2026-01-28"},{"cvss_score":9.1,"headline":"OpenProject has a SQL Injection via Custom Field Name that can be chained to Remote Code Execution","id":"CVE-2026-32698","kev_date_added":null,"published":"2026-03-18"},{"cvss_score":9.1,"headline":"OpenProject's repository files are served with the MIME type allowing them to be used to bypass Content Security Policy","id":"CVE-2026-32703","kev_date_added":null,"published":"2026-03-18"},{"cvss_score":9.1,"headline":"OpenProject is Vulnerable to Arbitrary File Read via ImageMagick SVG Coder","id":"CVE-2026-22600","kev_date_added":null,"published":"2026-01-10"},{"cvss_score":8.9,"headline":"OpenProject has SSRF and CSWSH in Hocuspocus Synchronization Server","id":"CVE-2026-24772","kev_date_added":null,"published":"2026-01-28"}],"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":["opf"]},"summary":"An attacker can cause a denial of service in OpenProject forums by submitting messages with unterminated pre tags that trigger excessive regex backtracking.","url":"https://insights.sbomify.com/CVE-2021-32763/"}
