An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2025-52691 and fix it if it is affected.\n\nWhat it is: CVE-2025-52691 is a critical vulnerability in SmarterTools SmarterMail, published on 29 Dec 2025. An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: Yes. Attackers have exploited CVE-2025-52691 in the wild since at least 26 Jan 2026, including in ransomware campaigns.\n\nAffected product: SmarterTools SmarterMail. 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-2025-52691/ (Markdown: https://insights.sbomify.com/CVE-2025-52691/index.md)","id":"CVE-2025-52691","markdown":"https://insights.sbomify.com/CVE-2025-52691/index.md","name":"CVE-2025-52691","record":{"aliases":["GHSA-c9vj-8fwr-4gvq"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"SmarterMail server","requires_auth":"none","summary":"Unauthenticated attackers can upload arbitrary files to any location on SmarterMail, potentially enabling remote code execution.","user_interaction":"not_required","vuln_class":"file_upload"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"CSA","cpe":[{"product":"smartermail","vendor":"smartertools"}],"cvss":{"score":10,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-434","name":"Unrestricted Upload of File with Dangerous Type"}],"description":"Successful exploitation of the vulnerability could allow an unauthenticated attacker to upload arbitrary files to any location on the mail server, potentially enabling remote code execution.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2025-10-09","github_poc":8,"max_poc_stars":19,"metasploit":1,"nuclei":1,"refs":[{"date":"2025-12-30T06:13:10Z","kind":"github_poc","ref":"https://github.com/rxerium/CVE-2025-52691","stars":19,"title":"Detection for CVE-2025-52691"},{"date":"2026-01-08T11:42:01Z","kind":"github_poc","ref":"https://github.com/watchtowrlabs/watchTowr-vs-SmarterMail-CVE-2025-52691","stars":19,"title":null},{"date":"2025-12-30T18:21:29Z","kind":"github_poc","ref":"https://github.com/DeathShotXD/CVE-2025-52691-APT-PoC","stars":5,"title":"An enhanced proof-of-concept exploit for CVE-2025-52691 (SmarterMail Arbitrary File Upload RCE) with APT-level features like stealth obfuscation, persistence, exfiltration, and interactive mode.
