{"cve":"CVE-2026-55434","nvd":{"published":"2026-07-07T21:17:27.290","modified":"2026-07-08T19:47:17.140","status":"Analyzed","description":"Coder allows organizations to provision remote development environments via Terraform. Starting in version 2.33.0 and prior to versions 2.33.8 and 2.34.2, AI Bridge provider handlers read request bodies with `io.ReadAll` without a maximum size so an authenticated user with AI Bridge access could send an arbitrarily large body and exhaust memory. Exploitation requires authenticated access to the AI Bridge endpoints and the impact is limited to availability (denial of service). Versions 2.33.8 and 2.34.2 patch the issue. No known workarounds are available.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","score":6.5},"cwes":["CWE-770"],"references":["https://github.com/coder/coder/pull/26164","https://github.com/coder/coder/releases/tag/v2.33.8","https://github.com/coder/coder/releases/tag/v2.34.2","https://github.com/coder/coder/security/advisories/GHSA-f5vp-w269-392g"],"products":["coder:coder"],"source":"nvd","synced_at":"2026-10-19T22:42:16.820116992+00:00"},"epss":{"cve":"CVE-2026-55434","score":0.00552,"percentile":0.46136,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-f5vp-w269-392g","url":"https://osv.dev/vulnerability/GHSA-f5vp-w269-392g","summary":"Coder vulnerable to denial of service via unbounded request body in AI Bridge provider endpoints","modified":"2026-07-07T22:30:08.855346479Z","packages":[{"ecosystem":"Go","name":"github.com/coder/coder/v2","purl":"pkg:golang/github.com/coder/coder/v2","ranges":[">=2.34.0 <2.34.2"],"fixed":["2.34.2"]},{"ecosystem":"Go","name":"github.com/coder/coder/v2","purl":"pkg:golang/github.com/coder/coder/v2","ranges":[">=2.33.0 <2.33.8"],"fixed":["2.33.8"]}]},{"id":"GO-2026-5921","url":"https://osv.dev/vulnerability/GO-2026-5921","summary":"Coder vulnerable to denial of service via unbounded request body in AI Bridge provider endpoints in github.com/coder/coder","modified":"2026-07-07T20:30:16.268444736Z","packages":[{"ecosystem":"Go","name":"github.com/coder/coder","purl":"pkg:golang/github.com/coder/coder","ranges":["all versions"],"fixed":[]},{"ecosystem":"Go","name":"github.com/coder/coder/v2","purl":"pkg:golang/github.com/coder/coder/v2","ranges":[">=2.33.0 <2.33.8",">=2.34.0 <2.34.2"],"fixed":["2.33.8","2.34.2"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
