Deeper analysis

An access control vulnerability exists in SoroushPlus+ Messenger version 1.0.30 within the Lock Screen Security Feature. The flaw stems from insufficient permissions and privileges (CWE-863) that allow unauthorized bypass of the lock screen function. It carries a CVSS 3.1 score of 9.1 reflecting network attack vector, low complexity, and no required authentication or user interaction.

An unauthenticated remote attacker can exploit the weakness to circumvent the lock screen, resulting in high impact to confidentiality and integrity while availability remains unaffected. The published EPSS score stands at 0.3049 with an identical peak value, indicating steady rather than rising exploitation probability since disclosure.
