Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-93903 in the wild and no public exploit code.\n\nAffected product: litespeedtech LiteSpeed Web Server. 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-2026-93903/ (Markdown: https://insights.sbomify.com/CVE-2026-93903/index.md)","id":"CVE-2026-93903","markdown":"https://insights.sbomify.com/CVE-2026-93903/index.md","name":"CVE-2026-93903","record":{"aliases":["GHSA-8x5w-4247-99g6"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"LiteSpeed Web Server","requires_auth":"low_privilege","summary":"An attacker can exploit mishandled internal redirect URL validation in LiteSpeed Web Server to bypass security controls.","user_interaction":"not_required","vuln_class":"open_redirect"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[],"cvss":{"score":9.4,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H","version":"4.0"},"cwes":[{"id":"CWE-174","name":"Double Decoding of the Same Data"}],"description":"LiteSpeed Web Server (LSWS) before 6.3.7 build 1 mishandles internal redirect URL validation in a certain \"corner case.\"","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2026-10-28","github_poc":1,"max_poc_stars":1,"metasploit":0,"nuclei":0,"refs":[{"date":"2026-10-28T17:11:17Z","kind":"github_poc","ref":"https://github.com/Tautvydas-Aleliunas/CVE-2026-93903","stars":1,"title":"Security advisory for CVE-2026-93903 affecting LiteSpeed Web Server."}],"tier":"poc_unverified"},"has_fix":null,"headline":"Open redirect in LiteSpeed Web Server","id":"CVE-2026-93903","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"open_redirect","year":"2026"},"n_packages":0,"n_references":3,"next":{"headline":"Social Web Suite \u003c= 4.1.12 - Unauthenticated SQL Injection via 'exclude_posts' Parameter","id":"CVE-2026-93904"},"packages":[],"prev":{"headline":"Privilege escalation in Optima Express IDX","id":"CVE-2026-93901"},"products":["LiteSpeed Web Server"],"published":"2026-09-30","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)"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-10-29","vendors":["litespeedtech"]},"summary":"An attacker can exploit mishandled internal redirect URL validation in LiteSpeed Web Server to bypass security controls.","url":"https://insights.sbomify.com/CVE-2026-93903/"}
