Prior to 6.2.1, Client.list() can be forced by a malicious or compromised FTP server to spend quadratic CPU time parsing a directory listing because the RE_LINE expression in src/parseListUnix.ts backtracks across adjacent variable-length owner and group fields when a long Unix-style line has a valid prefix but cannot satisfy the later size and date fields. parseList() selects a parser from the last nonblank line and then applies it to every line, so a normal final line can select the Unix parser while an earlier crafted line blocks the Node.js event loop and freezes the process. This issue is fixed in version 6.2.1.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.\n\n## Vendor advisories\n\n- **Red Hat VEX** · Important · affected: Red Hat Developer Hub, Red Hat Enterprise Linux AI (RHEL AI) 3, Red Hat OpenShift AI (RHOAI), Red Hat OpenShift GitOps, Self-service automation portal 2 · no fix planned: Red Hat OpenShift GitOps, Red Hat Developer Hub, Red Hat Enterprise Linux AI (RHEL AI) 3, Red Hat OpenShift AI (RHOAI), … · updated 2026-10-21 · [vex](https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-102990.json)\n- **RHSA-2026:86675** · Red Hat · fixed in: Red Hat Ansible Automation Platform 2.2 · released 2026-10-21 · [advisory](https://access.redhat.com/errata/RHSA-2026:86675)\n\n## Package advisory (CVE-2026-102990)\n\nAffected packages:\n\n- `basic-ftp <= 6.2.0`\n\nPatched in:\n\n- `basic-ftp 6.2.1`\n\nSource: https://github.com/advisories/GHSA-c475-qrg2-pj4r","depth":"midnight","depthScore":57,"depthScoreParts":{"impact":45.1,"likelihood":0.1,"exploitation":12,"ransomware":0},"changes":[{"seq":214036,"id":"CVE-2026-102990","ts":1790803615548,"field":"exploit_available","old":"false","new":"true"}]}
