An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2024-22640 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- tecnickcom/tcpdf (Packagist): affected all versions; fixed in 6.7.5\n- tecnickcom/tcpdf (Packagist): affected all versions; fixed in 6.7.5\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-2024-22640/ (Markdown: https://insights.sbomify.com/CVE-2024-22640/index.md)","id":"CVE-2024-22640","markdown":"https://insights.sbomify.com/CVE-2024-22640/index.md","name":"CVE-2024-22640","record":{"aliases":["DEBIAN-CVE-2024-22640","GHSA-mx3p-fhpw-x6rv","MGASA-2024-0169","UBUNTU-CVE-2024-22640"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"PHP PDF library","requires_auth":"none","summary":"Attackers can cause denial of service in TCPDF by providing crafted HTML with malicious color values, affecting applications using this library.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"fedora","vendor":"fedoraproject"},{"product":"tcpdf","vendor":"tcpdf_project"}],"cvss":{"score":7.5,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-1333","name":"Inefficient Regular Expression Complexity"}],"description":"TCPDF version \u003c=6.6.5 is vulnerable to ReDoS (Regular Expression Denial of Service) if parsing an untrusted HTML page with a crafted color.","ecosystems":["Packagist"],"exploits":{"exploitdb":0,"first_seen":"2024-04-01","github_poc":1,"max_poc_stars":0,"metasploit":0,"nuclei":0,"refs":[{"date":"2024-04-01T15:43:07Z","kind":"github_poc","ref":"https://github.com/zunak/CVE-2024-22640","stars":0,"title":null}],"tier":"poc_unverified"},"has_fix":true,"headline":"TCPDF vulnerable to Regular Expression Denial of Service","id":"CVE-2024-22640","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Packagist","product":"fedoraproject:fedora","products":["fedoraproject:fedora"],"type":"denial_of_service","year":"2024"},"n_packages":2,"n_references":3,"next":{"headline":"Denial of service in n/a","id":"CVE-2024-22641"},"packages":[{"ecosystem":"Packagist","fixed":["6.7.5"],"introduced":["0"],"last_affected":[],"package":"tecnickcom/tcpdf","purl":null,"source":"GHSA-mx3p-fhpw-x6rv"},{"ecosystem":"Packagist","fixed":["6.7.5"],"introduced":["0"],"last_affected":[],"package":"tecnickcom/tcpdf","purl":"pkg:composer/tecnickcom/tcpdf","source":"GHSA-mx3p-fhpw-x6rv"}],"prev":{"headline":"Cross-site scripting in n/a","id":"CVE-2024-22639"},"products":["n/a"],"published":"2024-04-19","related":[{"cvss_score":9.8,"headline":"PHP-CGI OS Command Injection","id":"CVE-2024-4577","kev_date_added":"2024-06-12","published":"2024-06-09"},{"cvss_score":9.8,"headline":"Grafana Authentication Bypass","id":"CVE-2021-39226","kev_date_added":"2022-08-25","published":"2021-10-05"},{"cvss_score":9.8,"headline":"VMware ESXi and Horizon DaaS OpenSLP Heap-Based Buffer Overflow","id":"CVE-2019-5544","kev_date_added":"2021-11-03","published":"2019-12-06"},{"cvss_score":9.6,"headline":"Google Chromium V8 Type Confusion","id":"CVE-2024-4947","kev_date_added":"2024-05-20","published":"2024-05-15"},{"cvss_score":9.6,"headline":"Google Chromium Visuals Use-After-Free","id":"CVE-2024-4671","kev_date_added":"2024-05-13","published":"2024-05-09"},{"cvss_score":9.6,"headline":"Google Chromium Mojo Insufficient Data Validation","id":"CVE-2022-3075","kev_date_added":"2022-09-08","published":"2022-09-26"},{"cvss_score":9.6,"headline":"Google Chromium Indexed DB API Use-After-Free","id":"CVE-2021-30633","kev_date_added":"2021-11-03","published":"2021-10-08"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"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":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-11-04","vendors":["n/a"]},"summary":"Attackers can cause denial of service in TCPDF by providing crafted HTML with malicious color values, affecting applications using this library.","url":"https://insights.sbomify.com/CVE-2024-22640/"}
