High-severity RCE in a widely used developer IDE (IntelliJ); could enable code execution on developer machines and lead to supply-chain or codebase compromise.
CVE-2026-59792
Path traversal in IntelliJ IDEA allows arbitrary code execution in affected versions.
Is CVE-2026-59792 being exploited?
Not confirmed. CVE-2026-59792 does not appear in CISA's Known Exploited Vulnerabilities catalog, which records only exploitation that has been observed and reported publicly.

As published in the CVE Program record. A version outside these ranges is not a statement that it is unaffected — vendors sometimes understate a range, and distribution-backported builds carry upstream numbers that do not reflect what was patched into them.
