When executing recursively (`-R` or `--recursive`) over multiple target paths, the utility fails to accumulate the overall exit status, overwriting error codes from early failures with the status of the final target. This results in false-success exit codes (0), potentially leading security automation and deployment scripts to assume permission modifications succeeded when they actually failed.\n\n## TL;DR\nA 'last-file-wins' logic vulnerability in Rust-based `chmod -R` permits silent failures, returning exit code 0 even if previous targets failed. This bypasses automated permission checks in scripts and CI/CD pipelines.\n\n## Technical Details\n\n- **CWE ID**: CWE-253 (Incorrect Check of Function Return Value)\n- **Attack Vector**: Local (AV:L)\n- **CVSS v3.1**: 5.5 (Medium)\n- **EPSS Score**: 0.00142 (3.90th percentile)\n- **Impact**: Integrity Loss (Silent permission-application bypasses)\n- **Exploit Status**: No public weaponized exploits available\n- **CISA KEV Status**: Not listed\n\n## Affected Systems\n\n- uutils/coreutils\n- **coreutils**: < 0.6.0 (Fixed in: `0.6.0`)\n\n## Mitigation\n\n- Upgrade uutils/coreutils to version 0.6.0 or later.\n- Deconstruct multi-argument recursive chmod operations in scripts into separate commands or chain them with explicit logical operators.\n- Implement defensive post-execution verification checks using test operators or find to validate that target permissions match expectations.\n\n**Remediation Steps:**\n1. Identify systems or container images using Rust uutils/coreutils.\n2. Update coreutils package to version 0.6.0 or higher.\n3. For active CI/CD pipelines, audit bash scripts or Ansible playbooks that invoke chmod with multiple recursive directory targets.\n4. Modify multi-target invocations to single-target invocations linked with '&&' if immediate upgrades are not possible.\n\n## References\n\n- [CVE-2026-35339 Record](https://www.cve.org/CVERecord?id=CVE-2026-35339)\n- [GitHub Pull Request 9793](https://github.com/uutils/coreutils/pull/9793)\n- [Security Fix Commit](https://github.com/uutils/coreutils/commit/abd581f62e97d0b147306ac40eac13af71c6fbba)\n- [uutils coreutils 0.6.0 Release](https://github.com/uutils/coreutils/releases/tag/0.6.0)\n- [Wiz Vulnerability Database Entry](https://www.wiz.io/vulnerability-database/cve/cve-2026-35339)\n\n\n---\n*Generated by [CVEReports](https://cvereports.com/reports/CVE-2026-35339) - Automated Vulnerability Intelligence*", "creation_timestamp": "2026-07-06T19:41:46.111341Z"} 2026-07-06T19:41:46.111341+00:00
