Prior to 5.12.7, a server-side code injection vulnerability existed in the Yamcs algorithm evaluation engine org.yamcs.algorithms.JavaExprAlgorithmExecutionFactory, which dynamically compiled and evaluated user-controlled algorithm text through the Janino compiler without enforcing a secure sandbox, so an authenticated user with the ChangeMissionDatabase privilege could override an existing algorithm's text via the mission database REST API and inject Java code (for example using java.lang.Runtime) to achieve remote code execution on the underlying host operating system. This issue is fixed in versions 5.12.7 and 5.13.0, which disable algorithm editing by default.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H","score":9.1},"cwes":["CWE-94"],"references":["https://github.com/yamcs/yamcs/commit/3c550348f866af4675d2ba4a51d8d12b7c7c6011","https://github.com/yamcs/yamcs/commit/4ff8fda642ea8c3309a4d3f379aa77b763148992","https://github.com/yamcs/yamcs/releases/tag/yamcs-5.12.7","https://github.com/yamcs/yamcs/releases/tag/yamcs-5.13.0","https://github.com/yamcs/yamcs/security/advisories/GHSA-524g-x36v-9wm6"],"products":["spaceapplications:yamcs"],"source":"nvd","synced_at":"2026-10-19T22:45:36.895656543+00:00"},"epss":{"cve":"CVE-2026-44632","score":0.01116,"percentile":0.66086,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-524g-x36v-9wm6","url":"https://osv.dev/vulnerability/GHSA-524g-x36v-9wm6","summary":"Yamcs Vulnerable to Server-Side Code Injection (RCE) via Janino Expression Engine in `JavaExprAlgorithmExecutionFactory`","modified":"2026-05-27T00:26:29.851308Z","packages":[{"ecosystem":"Maven","name":"org.yamcs:yamcs-core","purl":"pkg:maven/org.yamcs/yamcs-core","ranges":["<5.12.7"],"fixed":["5.12.7"]}]}],"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).
