CVE-2026-30814
A stack-based buffer overflow in the tmpServer module of TP-Link Archer AX53 v1.0 allows an authenticated adjacent attacker to trigger a segmentation fault and potentially execute arbitrary code via a specially crafted configuration file.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.42%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
A stack-based buffer overflow in the tmpServer module of TP-Link Archer AX53 v1.0 allows an authenticated adjacent attacker to trigger a segmentation fault and potentially execute arbitrary code via a specially crafted configuration file.
