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-2026-90871/ (Markdown: https://insights.sbomify.com/CVE-2026-90871/index.md)","id":"CVE-2026-90871","markdown":"https://insights.sbomify.com/CVE-2026-90871/index.md","name":"CVE-2026-90871","record":{"aliases":["GHSA-8298-7w39-fvv4"],"analysis":null,"analysis_generated_by":null,"assigner":"ProgressSoftware","cpe":[],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-73","name":"External Control of File Name or Path"},{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"Improper limitation of a pathname to a restricted directory in Progress Software WS_FTP Server versions prior to 2024.0.7 and 2025.0.4 on Windows could allow an unauthenticated attacker to affect files outside the intended directory.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Path Traversal Leading to File Deletion in Ad Hoc Transfer and Web Transfer in Progress WS_FTP Server","id":"CVE-2026-90871","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":null,"year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Server-Side Script Injection in Manager Web UI in Progress WS_FTP Server","id":"CVE-2026-90872"},"packages":[],"prev":{"headline":"Unauthenticated Ad Hoc Transfer Resource Exhaustion in Progress WS_FTP Server","id":"CVE-2026-90870"},"products":["WS_FTP Server"],"published":"2026-10-29","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":"2026-10-29","vendors":["Progress Software"]},"summary":null,"url":"https://insights.sbomify.com/CVE-2026-90871/"}
