Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-55435 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/coder/coder/v2 (Go): affected from 2.30.0; fixed in 2.32.7, 2.33.8, 2.34.2\n- github.com/coder/coder/v2 (Go): affected from 2.30.0; fixed in 2.32.7\n- github.com/coder/coder/v2 (Go): affected from 2.30.0; fixed in 2.32.7\n- github.com/coder/coder/v2 (Go): affected from 2.33.0; fixed in 2.33.8\n- github.com/coder/coder/v2 (Go): affected from 2.33.0; fixed in 2.33.8\n- github.com/coder/coder/v2 (Go): affected from 2.34.0; fixed in 2.34.2\n- github.com/coder/coder/v2 (Go): affected from 2.34.0; fixed in 2.34.2\n- github.com/coder/coder (Go): affected all versions; no fix listed\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-2026-55435/ (Markdown: https://insights.sbomify.com/CVE-2026-55435/index.md)","id":"CVE-2026-55435","markdown":"https://insights.sbomify.com/CVE-2026-55435/index.md","name":"CVE-2026-55435","record":{"aliases":["GHSA-wqxv-w64v-5wh6","GO-2026-5925"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Coder development platform","requires_auth":"low_privilege","summary":"Suspended Coder users retain access to AI Bridge LLM proxy endpoints because their API keys are not revoked upon suspension.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"coder","vendor":"coder"}],"cvss":{"score":5.4,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-863","name":"Incorrect Authorization"}],"description":"Coder allows organizations to provision remote development environments via Terraform. Starting in version 2.30.0 and prior to versions 2.32.7, 2.33.8, and 2.34.2, AI Bridge proxy endpoints authenticate via `Server.IsAuthorized` in `coderd/aibridgedserver`, which validates key format, expiry, secret and deleted or system users but does not check whether the account is suspended. Because suspension does not revoke existing API keys, a suspended user's unexpired token keeps working. Practical impact is limited to already-issued API keys of suspended users until those keys are deleted. Versions 2.32.7, 2.33.8, and 2.34.2 patch the issue. As a workaround, on suspension, delete the user's API keys via `DELETE /api/v2/users/{user}/keys`.","ecosystems":["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":"Suspended Coder users retain access to AI Bridge LLM proxy endpoints","id":"CVE-2026-55435","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Go","product":null,"products":[],"type":"auth_bypass","year":"2026"},"n_packages":8,"n_references":7,"next":{"headline":"Coder's AI Bridge Proxy skips TLS certificate verification in default configuration","id":"CVE-2026-55436"},"packages":[{"ecosystem":"Go","fixed":[],"introduced":["0"],"last_affected":[],"package":"github.com/coder/coder","purl":"pkg:golang/github.com/coder/coder","source":"GO-2026-5925"},{"ecosystem":"Go","fixed":["2.32.7","2.33.8","2.34.2"],"introduced":["2.30.0","2.33.0","2.34.0"],"last_affected":[],"package":"github.com/coder/coder/v2","purl":"pkg:golang/github.com/coder/coder/v2","source":"GO-2026-5925"},{"ecosystem":"Go","fixed":["2.32.7"],"introduced":["2.30.0"],"last_affected":[],"package":"github.com/coder/coder/v2","purl":null,"source":"GHSA-wqxv-w64v-5wh6"},{"ecosystem":"Go","fixed":["2.32.7"],"introduced":["2.30.0"],"last_affected":[],"package":"github.com/coder/coder/v2","purl":"pkg:golang/github.com/coder/coder/v2","source":"GHSA-wqxv-w64v-5wh6"},{"ecosystem":"Go","fixed":["2.33.8"],"introduced":["2.33.0"],"last_affected":[],"package":"github.com/coder/coder/v2","purl":null,"source":"GHSA-wqxv-w64v-5wh6"},{"ecosystem":"Go","fixed":["2.33.8"],"introduced":["2.33.0"],"last_affected":[],"package":"github.com/coder/coder/v2","purl":"pkg:golang/github.com/coder/coder/v2","source":"GHSA-wqxv-w64v-5wh6"},{"ecosystem":"Go","fixed":["2.34.2"],"introduced":["2.34.0"],"last_affected":[],"package":"github.com/coder/coder/v2","purl":null,"source":"GHSA-wqxv-w64v-5wh6"},{"ecosystem":"Go","fixed":["2.34.2"],"introduced":["2.34.0"],"last_affected":[],"package":"github.com/coder/coder/v2","purl":"pkg:golang/github.com/coder/coder/v2","source":"GHSA-wqxv-w64v-5wh6"}],"prev":{"headline":"Coder vulnerable to denial of service via unbounded request body in AI Bridge provider endpoints","id":"CVE-2026-55434"},"products":["coder"],"published":"2026-07-07","related":[{"cvss_score":9.1,"headline":"Coder: PKCS#7 signature bypass in Azure instance identity allows unauthenticated agent token theft","id":"CVE-2026-46354","kev_date_added":null,"published":"2026-07-07"},{"cvss_score":8.7,"headline":"Coder's workspace app upsert allows cross-workspace agent rebinding via user-controlled app ID","id":"CVE-2026-55429","kev_date_added":null,"published":"2026-07-08"},{"cvss_score":8.3,"headline":"Coder vulnerable to SSH config injection via unsanitized server-supplied values in `coder config-ssh`","id":"CVE-2026-55427","kev_date_added":null,"published":"2026-07-07"},{"cvss_score":8.2,"headline":"Coder: Route hijacking through lack of validation of agent-supplied AllowedIPs in tailnet coordinator","id":"CVE-2026-55428","kev_date_added":null,"published":"2026-07-07"},{"cvss_score":8.2,"headline":"Coder's OIDC authentication allows email with partially matching domain to register","id":"CVE-2024-27918","kev_date_added":null,"published":"2024-03-06"},{"cvss_score":8.1,"headline":"Coder vulnerable to workspace auto-creation via crafted URL parameters without user consent","id":"CVE-2026-44454","kev_date_added":null,"published":"2026-07-07"},{"cvss_score":8.1,"headline":"Coder's privilege escalation vulnerability could lead to a cross workspace compromise","id":"CVE-2025-58437","kev_date_added":null,"published":"2025-09-06"}],"sources":[{"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":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-07-09","vendors":["coder"]},"summary":"Suspended Coder users retain access to AI Bridge LLM proxy endpoints because their API keys are not revoked upon suspension.","url":"https://insights.sbomify.com/CVE-2026-55435/"}
