RUSTSEC-2026-0180 (GHSA-RGQC-3X5P-6GWG)
Vulnerability from osv_rustsec – Published: 2026-06-12 12:00 – Updated: 2026-08-25 02:42 – Source websiteA malicious or compromised server can return a binary hstore value with an
invalid internal length field, causing the client to panic while decoding it.
Applications that connect only to a trusted database are not exposed; the risk applies to clients that may connect to untrusted or user-supplied servers, or whose connection can be intercepted by a man-in-the-middle.
