CVE-2026-102521CVE-2026-102521

Description

The decoder in `readFromDataView` in lib0 before 0.2.119 can be tricked into reading more than it should from a buffer. The vulnerability allows reading past the decoders' view, thus exposing adjacent process memory. This can be anything that is currently in the head, for example credentials or logs. This is similar to but different from GHSA-r5c8-rf4w-qrq8.
