Broken access control in ACF Extended (WordPress plugin) through version 0.9.2.6 allows contributor-level authenticated users to perform privileged operations beyond their intended role boundaries. The root cause is CWE-862 (Missing Authorization): the plugin executes certain sensitive actions without verifying the requesting user holds sufficient permissions. No active exploitation or public proof-of-concept has been identified at time of analysis, but the low attack complexity and network accessibility make this straightforward to exploit for any user holding a contributor account on an affected site.
Integer overflow in U-Boot's SquashFS filesystem parser (fs/squashfs/sqfs.c, function sqfs_concat_tokens) enables heap under-allocation followed by a heap-based buffer overflow via strcpy() when a crafted SquashFS image with manipulated token lists is processed during boot. All U-Boot releases through v2026.01-rc4 are affected. No public exploit code and no CISA KEV listing have been identified at time of analysis; a confirmed fix is available in v2026.04-rc1 (commit adccdb2).
