An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2025-25294 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/envoyproxy/gateway (Go): affected all versions; fixed in 1.2.7, 1.3.1\n- github.com/envoyproxy/gateway (Go): affected all versions; fixed in 1.2.7\n- github.com/envoyproxy/gateway (Go): affected all versions; fixed in 1.2.7\n- github.com/envoyproxy/gateway (Go): affected from 1.3.0-rc.1; fixed in 1.3.1\n- github.com/envoyproxy/gateway (Go): affected from 1.3.0-rc.1; fixed in 1.3.1\n- envoy-gateway (Bitnami): affected all versions; fixed in 1.2.7, 1.3.1\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-2025-25294/ (Markdown: https://insights.sbomify.com/CVE-2025-25294/index.md)","id":"CVE-2025-25294","markdown":"https://insights.sbomify.com/CVE-2025-25294/index.md","name":"CVE-2025-25294","record":{"aliases":["BIT-envoy-gateway-2025-25294","CLEANSTART-2026-DL05775","CLEANSTART-2026-GL17744","GHSA-mf24-chxh-hmvj","GO-2025-3504"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Envoy Gateway","requires_auth":"none","summary":"Attackers can inject JSON into access logs via crafted user-agent strings, potentially corrupting log data in Envoy Gateway deployments.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"gateway","vendor":"envoyproxy"}],"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-117","name":"Improper Output Neutralization for Logs"}],"description":"Envoy Gateway is an open source project for managing Envoy Proxy as a standalone or Kubernetes-based application gateway. In all Envoy Gateway versions prior to 1.2.7 and 1.3.1 a default Envoy Proxy access log configuration is used. This format is vulnerable to log injection attacks. If the attacker uses a specially crafted user-agent which performs json injection, then he could add and overwrite fields to the access log. This vulnerability is fixed in 1.3.1 and 1.2.7. One can overwrite the old text based default format with JSON formatter by modifying the \"EnvoyProxy.spec.telemetry.accessLog\" setting.","ecosystems":["Bitnami","Go"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Envoy Gateway Log Injection Vulnerability","id":"CVE-2025-25294","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":null,"products":[],"type":"other","year":"2025"},"n_packages":6,"n_references":2,"next":{"headline":"Label Studio has a Path Traversal Vulnerability via image Field","id":"CVE-2025-25295"},"packages":[{"ecosystem":"Bitnami","fixed":["1.2.7","1.3.1"],"introduced":["0","1.3.0"],"last_affected":[],"package":"envoy-gateway","purl":"pkg:bitnami/envoy-gateway","source":"BIT-envoy-gateway-2025-25294"},{"ecosystem":"Go","fixed":["1.2.7","1.3.1"],"introduced":["0","1.3.0-rc.1"],"last_affected":[],"package":"github.com/envoyproxy/gateway","purl":"pkg:golang/github.com/envoyproxy/gateway","source":"GO-2025-3504"},{"ecosystem":"Go","fixed":["1.2.7"],"introduced":["0"],"last_affected":[],"package":"github.com/envoyproxy/gateway","purl":null,"source":"GHSA-mf24-chxh-hmvj"},{"ecosystem":"Go","fixed":["1.2.7"],"introduced":["0"],"last_affected":[],"package":"github.com/envoyproxy/gateway","purl":"pkg:golang/github.com/envoyproxy/gateway","source":"GHSA-mf24-chxh-hmvj"},{"ecosystem":"Go","fixed":["1.3.1"],"introduced":["1.3.0-rc.1"],"last_affected":[],"package":"github.com/envoyproxy/gateway","purl":null,"source":"GHSA-mf24-chxh-hmvj"},{"ecosystem":"Go","fixed":["1.3.1"],"introduced":["1.3.0-rc.1"],"last_affected":[],"package":"github.com/envoyproxy/gateway","purl":"pkg:golang/github.com/envoyproxy/gateway","source":"GHSA-mf24-chxh-hmvj"}],"prev":{"headline":"ruby-saml vulnerable to Remote Denial of Service (DoS) with compressed SAML responses","id":"CVE-2025-25293"},"products":["gateway"],"published":"2025-03-06","related":[{"cvss_score":8.8,"headline":"Envoy Extension Policy lua scripts injection causes arbitrary command execution","id":"CVE-2026-22771","kev_date_added":null,"published":"2026-01-12"},{"cvss_score":7.1,"headline":"Envoy Admin Interface Exposed through prometheus metrics endpoint","id":"CVE-2025-24030","kev_date_added":null,"published":"2025-01-23"}],"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":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"CC BY 4.0","name":"Go Vulnerability Database","prefix":"GO"},{"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":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-03-06","vendors":["envoyproxy"]},"summary":"Attackers can inject JSON into access logs via crafted user-agent strings, potentially corrupting log data in Envoy Gateway deployments.","url":"https://insights.sbomify.com/CVE-2025-25294/"}
