Name of the Vulnerable Software and Affected Versions Hermes versions prior to commit a6dcafe6ded8e61658b40f5699878cd19a481f80

Description A use-after-free in BigIntPrimitive addition could have been used by an attacker to leak raw data from Hermes VM’s heap. This issue is only exploitable in cases where Hermes is used to execute untrusted JavaScript. Most React Native applications are not affected.

Recommendations For versions prior to commit a6dcafe6ded8e61658b40f5699878cd19a481f80, update to a version that includes the fix for this issue. As a temporary workaround, consider restricting the execution of untrusted JavaScript in Hermes to minimize the risk of exploitation.
