Operationally, ranked in the top 3.2% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
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.

Defining permitted attribute values and auditing modifications reduces the chance of incorrect authorization outcomes due to tampered or missing labels.
The authorization process and usage restrictions help prevent incorrect authorization for remote access types.
Establishing configuration and connection requirements helps ensure correct rather than incorrect authorization for wireless access.
Establishing connection authorization processes for mobile devices helps ensure authorization decisions are correctly implemented rather than incorrect.
Monitoring account use, notifying on changes, and reviewing accounts for compliance corrects incorrect authorization assignments.
Ensures authorization decisions for external system use are correctly implemented and enforced.
