CVE-2025-55305
In versions below 35.7.5, 36.0.0-alpha.1 through 36.8.0, 37.0.0-alpha.1 through 37.3.1 and 38.0.0-alpha.1 through 38.0.0-beta.6, ASAR Integrity Bypass via resource modification.
Does this matter?
Lower severity and a low EPSS score (0.27%). Track it; it rarely justifies an emergency change on its own.
