Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2025-15554 is a vulnerability in Truesec’s LAPSWebUI prior to version 2.4 that enables browser caching of Local Administrator Password Solution (LAPS) passwords. This flaw allows attackers to retrieve cached credentials from the browser, leading to privilege escalation through disclosure of local administrator passwords. The issue is classified under CWE-525 and carries a CVSS v3.1 base score of 7.8 (AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H), indicating high impact with local access and low privileges required.
An attacker with physical or logical access to a workstation running the affected LAPSWebUI can exploit this vulnerability without user interaction. By accessing the browser's cache or storage, they can extract LAPS passwords for local administrators, enabling privilege escalation to full administrative control on the target system. This scenario is particularly relevant in environments where LAPSWebUI is deployed for password management across workstations.
The advisory published by Reversec Labs details mitigation strategies, recommending an upgrade to LAPSWebUI version 2.4 or later to address the caching issue (https://labs.reversec.com/advisories/2026/03/admin-passwords-cached-by-browsers-in-truesec-lapswebui). Security practitioners should verify browser cache clearing practices and monitor for unauthorized access to affected workstations.

Endpoint device configuration can enforce cache-clearing or no-cache policies for sensitive web content.
Application security requirements can explicitly require no-cache headers or cache-control directives for sensitive pages.
Secure coding standards can mandate proper cache-control headers and form-field handling to prevent sensitive data retention.
Configuration management can mandate secure browser cache settings across the estate.
Web filtering can block risky sites but does not directly govern browser caching of sensitive data.
