Playwright

Signature verification bypass in Microsoft Playwright lets an unauthenticated attacker holding an adjacent-network position (same LAN/Wi-Fi segment or an on-path interception point) present forged, signed-looking content that the library accepts as legitimate, enabling spoofing. Because the impact is primarily on data integrity (per the assessed vector AV:A/AC:H/PR:N/UI:N/S:U/C:L/I:H/A:N), the practical effect is attacker-controlled content being trusted by Playwright rather than direct remote code execution. Exploitation is constrained: the attacker must first obtain network adjacency and win a high-complexity interception/timing opportunity, no public exploit has been identified at time of analysis, and EPSS is low at 0.23% (13th percentile); Microsoft has published a vendor patch and the MSRC advisory should be consulted to confirm the exact affected feature.
