Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-26601 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- impresscms/impresscms (Packagist): affected all versions; fixed in 1.4.3\n- impresscms/impresscms (Packagist): affected all versions; fixed in 1.4.3\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-2021-26601/ (Markdown: https://insights.sbomify.com/CVE-2021-26601/index.md)","id":"CVE-2021-26601","markdown":"https://insights.sbomify.com/CVE-2021-26601/index.md","name":"CVE-2021-26601","record":{"aliases":["GHSA-4q96-9f63-p7jj"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_read","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"ImpressCMS","requires_auth":"low_privilege","summary":"Attackers can exploit a directory traversal vulnerability in ImpressCMS to read or modify arbitrary files on the server.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"impresscms","vendor":"impresscms"}],"cvss":{"score":8.1,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"ImpressCMS before 1.4.3 allows libraries/image-editor/image-edit.php image_temp Directory Traversal.","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":"Path Traversal in ImpressCMS","id":"CVE-2021-26601","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Packagist","product":null,"products":[],"type":"path_traversal","year":"2021"},"n_packages":2,"n_references":4,"next":{"headline":"bandisoft ARK library heap overflow vulnerability","id":"CVE-2021-26603"},"packages":[{"ecosystem":"Packagist","fixed":["1.4.3"],"introduced":["0"],"last_affected":[],"package":"impresscms/impresscms","purl":null,"source":"GHSA-4q96-9f63-p7jj"},{"ecosystem":"Packagist","fixed":["1.4.3"],"introduced":["0"],"last_affected":[],"package":"impresscms/impresscms","purl":"pkg:composer/impresscms/impresscms","source":"GHSA-4q96-9f63-p7jj"}],"prev":{"headline":"Type Confusion in ImpressCMS","id":"CVE-2021-26600"},"products":["n/a"],"published":"2022-03-28","related":[{"cvss_score":10,"headline":"Multiple unspecified vulnerabilities in ImpressCMS 1.0 have unknown impact and attack vectors, related to modules/admin.php and \"a few files","id":"CVE-2008-3453","kev_date_added":null,"published":"2008-08-04"},{"cvss_score":9.8,"headline":"SQL Injection in ImpressCMS","id":"CVE-2021-26599","kev_date_added":null,"published":"2022-03-28"},{"cvss_score":9.8,"headline":"Type Confusion in ImpressCMS","id":"CVE-2021-26600","kev_date_added":null,"published":"2022-03-28"},{"cvss_score":9.8,"headline":"Path Traversal in ImpressCMS","id":"CVE-2022-24977","kev_date_added":null,"published":"2022-02-13"},{"cvss_score":9.3,"headline":"ImpressCMS 1.4.4 - Unrestricted File Upload","id":"CVE-2022-50912","kev_date_added":null,"published":"2026-01-13"},{"cvss_score":7.5,"headline":"SQL injection in n/a","id":"CVE-2010-4271","kev_date_added":null,"published":"2010-11-16"}],"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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-03","vendors":["n/a"]},"summary":"Attackers can exploit a directory traversal vulnerability in ImpressCMS to read or modify arbitrary files on the server.","url":"https://insights.sbomify.com/CVE-2021-26601/"}
