Any signed-in user can exploit it over the network, 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-2025-55162 exists.\n\nAffected packages and fixed versions:\n- envoy (Bitnami): affected all versions; fixed in 1.32.10, 1.33.7, 1.34.5, 1.35.1\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-2025-55162/ (Markdown: https://insights.sbomify.com/CVE-2025-55162/index.md)","id":"CVE-2025-55162","markdown":"https://insights.sbomify.com/CVE-2025-55162/index.md","name":"CVE-2025-55162","record":{"aliases":["BIT-envoy-2025-55162","GHSA-95j4-hw7f-v2rh"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["account_takeover","security_bypass"],"network_reachable":"yes","non_default_config":true,"product_category":"Envoy proxy","requires_auth":"low_privilege","summary":"Envoy OAuth2 filter fails to clear secure cookies on logout, allowing session hijacking on shared computers if specific cookie prefixes are used.","user_interaction":"required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"envoy","vendor":"envoyproxy"}],"cvss":{"score":6.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:H/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-613","name":"DEPRECATED: Insufficient Session Expiration"}],"description":"Envoy is an open source L7 proxy and communication bus designed for large modern service oriented architectures. In versions below 1.32.10 and 1.33.0 through 1.33.6, 1.34.0 through 1.34.4 and 1.35.0, insufficient Session Expiration in the Envoy OAuth2 filter leads to failed logout operations. When configured with __Secure- or __Host- prefixed cookie names, the filter fails to append the required Secure attribute to the Set-Cookie header during deletion. Modern browsers ignore this invalid request, causing the session cookie to persist. This allows a user to remain logged in after they believe they have logged out, creating a session hijacking risk on shared computers. The current implementation iterates through the configured cookie names to generate deletion headers but does not check for these prefixes. This failure to properly construct the deletion header means the user's session cookies are never removed by the browser, leaving the session active and allowing the next user of the same browser to gain unauthorized access to the original user's account and data. This is fixed in versions 1.32.10, 1.33.7, 1.34.5 and 1.35.1.","ecosystems":["Bitnami"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":true,"headline":"Envoy: oAuth2 Filter Signout route will not clear cookies because of missing \"secure;\" flag","id":"CVE-2025-55162","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":"envoyproxy:envoy","products":["envoyproxy:envoy"],"type":"security_feature_bypass","year":"2025"},"n_packages":1,"n_references":2,"next":{"headline":"Netty MadeYouReset HTTP/2 DDoS Vulnerability","id":"CVE-2025-55163"},"packages":[{"ecosystem":"Bitnami","fixed":["1.32.10","1.33.7","1.34.5","1.35.1"],"introduced":["0","1.33.0","1.34.0","1.35.0"],"last_affected":[],"package":"envoy","purl":"pkg:bitnami/envoy","source":"BIT-envoy-2025-55162"}],"prev":{"headline":"Stirling-PDF SSRF vulnerability on /api/v1/convert/markdown/pdf","id":"CVE-2025-55161"},"products":["envoy"],"published":"2025-09-03","related":[{"cvss_score":10,"headline":"Trivial authentication bypass in Envoy","id":"CVE-2022-29226","kev_date_added":null,"published":"2022-06-09"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2019-18801","kev_date_added":null,"published":"2019-12-13"},{"cvss_score":9.8,"headline":"Security feature bypass in n/a","id":"CVE-2019-18802","kev_date_added":null,"published":"2019-12-13"},{"cvss_score":8.8,"headline":"Information disclosure in n/a","id":"CVE-2020-35470","kev_date_added":null,"published":"2020-12-15"},{"cvss_score":8.6,"headline":"Envoy ext auth can be bypassed when Proxy protocol filter sets invalid UTF-8 metadata","id":"CVE-2024-23324","kev_date_added":null,"published":"2024-02-09"},{"cvss_score":8.6,"headline":"Envoy vulnerable to OAuth2 credentials exploit with permanent validity","id":"CVE-2023-35941","kev_date_added":null,"published":"2023-07-25"},{"cvss_score":8.6,"headline":"Incorrect handling of H2 GOAWAY + SETTINGS frames","id":"CVE-2021-39162","kev_date_added":null,"published":"2021-09-09"}],"sources":[{"class":"attribution","licence":"Apache-2.0","name":"Bitnami","prefix":"BIT"},{"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":"partial"},"state":"PUBLISHED","updated":"2025-09-04","vendors":["envoyproxy"]},"summary":"Envoy OAuth2 filter fails to clear secure cookies on logout, allowing session hijacking on shared computers if specific cookie prefixes are used.","url":"https://insights.sbomify.com/CVE-2025-55162/"}
