{"id":"CVE-2026-45311","summary":"CodeWhale: run_tests Tool Enables RCE via Malicious Repository Without Approval","details":"CodeWhale is a DeepSeek + MiMo coding agent in terminal. From 0.3.0 to 0.8.23, the run_tests tool executes cargo test in the workspace with ApprovalRequirement::Auto, meaning it runs without any user approval prompt. cargo test compiles and executes arbitrary code: test binaries, build.rs build scripts, and proc macros. While auto-approving test execution is a deliberate design choice, it creates an inconsistency in the security boundary. However, in a malicious repository, test code can execute arbitrary shell commands, exfiltrate credentials, or establish persistence with zero approval. The attack is amplified by AGENTS.md (auto-loaded into the system prompt), which can instruct the model to run tests proactively at session start. This vulnerability is fixed in 0.8.23.","aliases":["GHSA-wx44-2q6h-j6p8"],"modified":"2026-07-08T08:13:29.491091191Z","published":"2026-05-28T17:32:26.950Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-94"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/45xxx/CVE-2026-45311.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/45xxx/CVE-2026-45311.json"},{"type":"ADVISORY","url":"https://github.com/Hmbown/CodeWhale/security/advisories/GHSA-wx44-2q6h-j6p8"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-45311"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/hmbown/codewhale","events":[{"introduced":"3204f556af2cf5f0bcc604fb9fd230b3a5a2e965"},{"fixed":"cfb5f08ae515f8dcf93aa10bdcf37dff3549e7ec"}],"database_specific":{"source":"AFFECTED_FIELD","extracted_events":[{"introduced":"0.3.0"},{"fixed":"0.8.23"}]}}],"versions":["v0.8.22","v0.8.21","v0.8.20","v0.8.19","v0.8.18","v0.8.17","v0.8.15","v0.8.14","v0.8.13","v0.8.12","v0.8.11","v0.8.10","v0.8.9","v0.8.8","v0.8.7","v0.8.6","v0.8.5","v0.8.4","v0.8.3","v0.8.2","v0.8.1","v0.8.0","v0.7.9","v0.7.8","v0.7.7","v0.7.6","v0.7.5","v0.7.4","v0.7.2","v0.7.1","v0.7.0","v0.6.7","v0.6.6","v0.6.5","v0.6.4","v0.6.3","v0.6.2","v0.6.1","v0.5.2","v0.5.1","v0.5.0","v0.4.9","v0.4.8","v0.4.7","v0.4.6","v0.4.5","v0.4.4","v0.4.3","v0.4.2","v0.4.1","v0.4.0","v0.3.33","v0.3.32","v0.3.31","v0.3.28","v0.3.27","v0.3.26","v0.3.25","v0.3.24","v0.3.23","v0.3.22","v0.3.21","v0.3.20","v0.3.19","v0.3.18","v0.3.17","v0.3.16","v0.3.14","v0.3.13","v0.3.12","v0.3.11","v0.3.10","v0.3.5","v0.3.4","v0.3.3","v0.3.2","v0.3.1","v0.3.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-45311.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H"}]}
