What's Changed

🔒 Security

This release fixes several more security vulnerabilities which are related to the fixes in v0.5.14. Please see the linked security advisories for more information.

• (moderate) Command Injection via non-synchronizing literal in "raw" argument (CVE-2026-47240, GHSA-8p34-64r3-mwg8)
  This vulnerability depends how the server interprets non-synchronizing literals.
  The connection is not vulnerable if the server supports non-synchronizing literals.
  • 🥅 Validate non-synchronizing literals support by @nevans in #703 (backports #701)
• (moderate) Command Injection via unvalidated ID and ENABLE arguments (CVE-2026-47242, GHSA-46q3-7gv7-qmgg)
  • 🥅 Validate ID values contain only valid bytes by @nevans in #703 (backports #698)
  • 🥅 Validate #enable arguments are all atoms by @nevans in #703 (backport #699)
    NOTE: #enable should never be called with untrusted input.
• (low) Denial of Service via incomplete "raw" argument validation (CVE-2026-47241, GHSA-c4fp-cxrr-mj66)
  This results in the affected command hanging until the connection is closed. If another thread attempts to send a concurrent pipelined command, the first thread will return with a syntax error and the second thread will hang until the connection closes.
  • Reported by @fg0x0
  • 🐛 Prevent trailing {0} in RawData validation by @nevans in #703 (backports #700)
