An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2026-81730 and fix it if it is affected.\n\nWhat it is: CVE-2026-81730 is a high-severity path traversal vulnerability in Dolibarr Dolibarr Erp\\/Crm, published on 27 Aug 2026. 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-2026-81730 in the wild and no public exploit code.\n\nAffected product: Dolibarr Dolibarr Erp\\/Crm. 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-2026-81730/ (Markdown: https://insights.sbomify.com/CVE-2026-81730/index.md)","id":"CVE-2026-81730","markdown":"https://insights.sbomify.com/CVE-2026-81730/index.md","name":"CVE-2026-81730","record":{"aliases":["GHSA-jgch-2jr2-87vj"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_modify","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Dolibarr ERP/CRM","requires_auth":"none","summary":"Attackers can write arbitrary files via email attachment filenames, potentially executing code or corrupting documents in Dolibarr.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[{"product":"dolibarr_erp\\/crm","vendor":"dolibarr"}],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:H/VA:L/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"Dolibarr 9.0.0 through 23.0.4 saves inbound email attachments under the name supplied in the message's MIME headers without reducing it to a safe basename. The global saveAttachment() in htdocs/emailcollector/lib/emailcollector.lib.php builds $filepath = $path . $filename . '.' . $ext and hands it to file_put_contents(), and the private saveAttachment() in htdocs/emailcollector/class/emailcollector.class.php writes to $destdir.'/'.$filename; the name reaches both from the attachment's own getName() or getFilename() value by way of the record-join, create-ticket and create-project operations. A traversal sequence in the filename therefore survives intact, so any sender who can email a mailbox that an EmailCollector monitors, which is the module's ordinary use for a support or ticket inbox, can place attacker-controlled content outside the per-object attachment directory without holding a Dolibarr account. Under the hardened layout Dolibarr's SECURITY.md requires, with htdocs read-only, the write is confined to the documents tree and corrupts or forges other objects' documents; where htdocs is writable the same primitive reaches a web-executable path. Version 24.0.0 applies dol_sanitizePathName() and dol_sanitizeFileName() before the write.","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":"Dolibarr 9.0.0 through 23.0.4 Path Traversal via EmailCollector Attachment Filename","id":"CVE-2026-81730","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"dolibarr:dolibarr_erp\\/crm","products":["dolibarr:dolibarr_erp\\/crm"],"type":"path_traversal","year":"2026"},"n_packages":0,"n_references":4,"next":{"headline":"Frappe 15.11.0 through 16.32.0 Stored XSS via Workspace Link Description","id":"CVE-2026-81731"},"packages":[],"prev":{"headline":"Dolibarr before 23.0.4 Incorrect Authorization on REST API Document Deletion","id":"CVE-2026-81729"},"products":["dolibarr"],"published":"2026-08-27","related":[{"cvss_score":9.8,"headline":"Dolibarr vulnerable to privilege escalation","id":"CVE-2022-43138","kev_date_added":null,"published":"2022-11-17"},{"cvss_score":9.8,"headline":"Dolibarr vulnerable to Eval Injection","id":"CVE-2022-40871","kev_date_added":null,"published":"2022-10-12"},{"cvss_score":9.8,"headline":"Dolibarr remote PHP code execution","id":"CVE-2021-33816","kev_date_added":null,"published":"2021-11-10"},{"cvss_score":9.8,"headline":"Dolibarr Improper Restriction of Excessive Authentication Attempts","id":"CVE-2020-7995","kev_date_added":null,"published":"2020-01-26"},{"cvss_score":9.8,"headline":"SQL injection in dolibarr","id":"CVE-2013-2091","kev_date_added":null,"published":"2019-11-20"},{"cvss_score":9.8,"headline":"Command injection in dolibarr","id":"CVE-2013-2093","kev_date_added":null,"published":"2019-11-20"},{"cvss_score":9.8,"headline":"Dolibarr SQL injection vulnerability in product/card.php","id":"CVE-2018-13447","kev_date_added":null,"published":"2018-07-08"}],"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":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-09-24","vendors":["Dolibarr"]},"summary":"Attackers can write arbitrary files via email attachment filenames, potentially executing code or corrupting documents in Dolibarr.","url":"https://insights.sbomify.com/CVE-2026-81730/"}
