{"id":"CVE-2026-45311","aliases":["GHSA-wx44-2q6h-j6p8"],"url":"https://o3.security/vulnerability/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.","published":"2026-05-28T17:32:26.950Z","modified":"2026-08-12T03:51:33.449933744Z","cvss":{"score":9.6,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H"},"epss":{"score":0.00375,"percentile":0.30251,"asOf":"2026-08-10"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"crates.io","name":"deepseek-tui","fixedVersion":"0.8.23"},{"ecosystem":"crates.io","name":"deepseek-tui-cli","fixedVersion":"0.8.23"},{"ecosystem":"npm","name":"deepseek-tui","fixedVersion":"0.8.23"}],"fix":null,"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"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:33.449933744Z"}}
