An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-54915 exists.\n\nAffected product: Tautulli. 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-2026-54915/ (Markdown: https://insights.sbomify.com/CVE-2026-54915/index.md)","id":"CVE-2026-54915","markdown":"https://insights.sbomify.com/CVE-2026-54915/index.md","name":"CVE-2026-54915","record":{"aliases":["GHSA-7c9r-fhj9-87xm"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Plex monitoring tool","requires_auth":"none","summary":"Attackers can redirect users to malicious sites via crafted links in Tautulli, enabling phishing or session abuse.","user_interaction":"required","vuln_class":"open_redirect"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":5.4,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-601","name":"URL Redirection to Untrusted Site"}],"description":"Tautulli is a Python based monitoring and tracking tool for Plex Media Server. Prior to 2.17.2, the unauthenticated /auth/redirect endpoint in plexpy/webauth.py removes forward slashes from the user-controlled redirect_uri parameter but leaves tab, line-feed, and carriage-return characters intact. With the default root HTTP_ROOT configuration, CherryPy HTTPRedirect passes the resulting value to urllib.parse.urljoin, which can resolve the whitespace-bearing path to an attacker-controlled external origin. A user who follows a crafted link can therefore be redirected outside Tautulli for phishing or post-login redirect-flow abuse, while custom non-root HTTP_ROOT configurations are not affected by this bypass. This issue is fixed in version 2.17.2.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":false,"headline":"Tautulli: Open redirect via whitespace bypass in /auth/redirect","id":"CVE-2026-54915","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":"Code injection in devicetype-library","id":"CVE-2026-54916"},"packages":[],"prev":{"headline":"UltraJSON: Malformed/Truncated UTF-8 Accepted and Silently Rewritten in ujson.dumps()","id":"CVE-2026-54911"},"products":["Tautulli"],"published":"2026-09-21","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":"no","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-09-24","vendors":["Tautulli"]},"summary":"Attackers can redirect users to malicious sites via crafted links in Tautulli, enabling phishing or session abuse.","url":"https://insights.sbomify.com/CVE-2026-54915/"}
