An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-28505 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-2026-28505/ (Markdown: https://insights.sbomify.com/CVE-2026-28505/index.md)","id":"CVE-2026-28505","markdown":"https://insights.sbomify.com/CVE-2026-28505/index.md","name":"CVE-2026-28505","record":{"aliases":["GHSA-m62j-gwm9-7p8m"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Plex monitoring tool","requires_auth":"high_privilege","summary":"Attackers can execute arbitrary code by bypassing the eval sandbox in Tautulli notification templates using nested lambda scopes.","user_interaction":"not_required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"tautulli","vendor":"tautulli"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:H/AT:N/PR:H/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-95","name":"Improper Neutralization of Directives in Dynamically Evaluated Code"},{"id":"CWE-94","name":"Improper Control of Generation of Code"}],"description":"Tautulli is a Python based monitoring and tracking tool for Plex Media Server. Prior to version 2.17.0, the str_eval() function in notification_handler.py implements a sandboxed eval() for notification text templates. The sandbox attempts to restrict callable names by inspecting code.co_names of the compiled code object. However, co_names only contains names from the outer code object. When a lambda expression is used, it creates a nested code object whose attribute accesses are stored in code.co_consts, NOT in code.co_names. The sandbox never inspects nested code objects. This issue has been patched in version 2.17.0.","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: RCE via eval() sandbox bypass using lambda nested scope to escape co_names whitelist check","id":"CVE-2026-28505","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"code_injection","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"Outline's Information Disclosure in Activity Logs allows User Enumeration of Private Drafts","id":"CVE-2026-28506"},"packages":[],"prev":{"headline":"Tandoor Recipes has Cross-Space IDOR in SyncViewSet.query_synced_folder: missing space scoping on get_object_or_404","id":"CVE-2026-28503"},"products":["Tautulli"],"published":"2026-03-30","related":[{"cvss_score":9.1,"headline":"Tautulli vulnerable to Authenticated Remote Code Execution via write primitive and `Script` notification agent","id":"CVE-2025-58762","kev_date_added":null,"published":"2025-09-09"},{"cvss_score":8.7,"headline":"Tautulli: Unauthenticated Path Traversal in `/newsletter/image/images` endpoint","id":"CVE-2026-31831","kev_date_added":null,"published":"2026-03-30"},{"cvss_score":8.6,"headline":"Tautulli vulnerable to Unauthenticated Path Traversal in `/image` endpoint","id":"CVE-2025-58760","kev_date_added":null,"published":"2025-09-09"},{"cvss_score":8.6,"headline":"Tautulli vulnerable to Unauthenticated Path Traversal in `real_pms_image_proxy`","id":"CVE-2025-58761","kev_date_added":null,"published":"2025-09-09"},{"cvss_score":8.1,"headline":"Tautulli vulnerable to Authenticated Remote Code Execution via Command Injection","id":"CVE-2025-58763","kev_date_added":null,"published":"2025-09-09"},{"cvss_score":7.4,"headline":"Tautulli: Unsanitized JSONP callback parameter allows cross-origin script injection and API key theft","id":"CVE-2026-32275","kev_date_added":null,"published":"2026-03-30"}],"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":"no","exploitation":"poc","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-03-30","vendors":["Tautulli"]},"summary":"Attackers can execute arbitrary code by bypassing the eval sandbox in Tautulli notification templates using nested lambda scopes.","url":"https://insights.sbomify.com/CVE-2026-28505/"}
