inngest is vulnerable to Observable Timing Discrepancy
25
Low Risk
This Affects:
inngestTL;DR
Affected versions of the package are vulnerable because request signature verification compared HMAC signatures using non-constant-time string comparison (such as ===/!==). This allowed attackers to exploit timing differences to recover or distinguish valid signatures. Additionally, insufficient timestamp validation allowed non-numeric or out-of-range values, which could enable bypass of expiry checks.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range.
