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-2024-56522 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- tecnickcom/tcpdf (Packagist): affected all versions; fixed in 6.8.0\n- tecnickcom/tcpdf (Packagist): affected all versions; fixed in 6.8.0\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-2024-56522/ (Markdown: https://insights.sbomify.com/CVE-2024-56522/index.md)","id":"CVE-2024-56522","markdown":"https://insights.sbomify.com/CVE-2024-56522/index.md","name":"CVE-2024-56522","record":{"aliases":["DEBIAN-CVE-2024-56522","GHSA-w95c-7994-ghpr","UBUNTU-CVE-2024-56522"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"PHP PDF library","requires_auth":"none","summary":"An attacker can bypass TCPDF tag hash verification due to insecure loose comparison, potentially compromising document integrity.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"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:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-843","name":"Access of Resource Using Incompatible Type"}],"description":"An issue was discovered in TCPDF before 6.8.0. unserializeTCPDFtag uses != (aka loose comparison) and does not use a constant-time function to compare TCPDF tag hashes.","ecosystems":["Packagist"],"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":"TCPDF has incorrect comparison","id":"CVE-2024-56522","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Packagist","product":null,"products":[],"type":"other","year":"2024"},"n_packages":2,"n_references":4,"next":{"headline":"Security feature bypass in n/a","id":"CVE-2024-56523"},"packages":[{"ecosystem":"Packagist","fixed":["6.8.0"],"introduced":["0"],"last_affected":[],"package":"tecnickcom/tcpdf","purl":null,"source":"GHSA-w95c-7994-ghpr"},{"ecosystem":"Packagist","fixed":["6.8.0"],"introduced":["0"],"last_affected":[],"package":"tecnickcom/tcpdf","purl":"pkg:composer/tecnickcom/tcpdf","source":"GHSA-w95c-7994-ghpr"}],"prev":{"headline":"TCPDF missing certificate validation","id":"CVE-2024-56521"},"products":["tcpdf"],"published":"2024-12-27","related":[{"cvss_score":9.8,"headline":"TCPDF missing certificate validation","id":"CVE-2024-56521","kev_date_added":null,"published":"2024-12-27"},{"cvss_score":7.5,"headline":"TCPDF lacks SVG sanitization","id":"CVE-2024-56519","kev_date_added":null,"published":"2024-12-27"},{"cvss_score":7.5,"headline":"TCPDF missing character escape on error messages","id":"CVE-2024-56527","kev_date_added":null,"published":"2024-12-27"},{"cvss_score":7.5,"headline":"Denial of service in n/a","id":"CVE-2024-22641","kev_date_added":null,"published":"2024-05-28"},{"cvss_score":7.5,"headline":"Server-side request forgery in n/a","id":"CVE-2017-6100","kev_date_added":null,"published":"2017-02-23"},{"cvss_score":6.2,"headline":"TCPDF Local File Inclusion vulnerability","id":"CVE-2024-51058","kev_date_added":null,"published":"2024-11-26"}],"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)"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-11-03","vendors":["tecnick"]},"summary":"An attacker can bypass TCPDF tag hash verification due to insecure loose comparison, potentially compromising document integrity.","url":"https://insights.sbomify.com/CVE-2024-56522/"}
