Secure Access: Out-of-bounds Read
CVE-2026-33451 is a high-severity out-of-bounds read vulnerability in Secure Access from Absolute Software, with a CVSS 3.1 base score of 7.8 out of 10. It can be exploited with local access to the system by an attacker with a low-privileged account, without any action from a user. The record lists version 14.50 as the first without the flaw, so updating Secure Access to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.1% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
