paragonie/sodium_compat is vulnerable to Incomplete List of Disallowed Inputs
45
Medium Risk
This Affects:
paragonie/sodium_compatTL;DR
Affected versions of this package are vulnerable to improper validation of Ed25519 elliptic-curve points due to a flaw in crypto_core_ed25519_is_valid_point(), which fails to correctly reject certain invalid inputs. This can lead to incorrect behavior in applications that directly rely on this low-level function with untrusted data. High-level cryptographic APIs are not impacted.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range.
Background info
paragonie/sodium_compat is vulnerable to Incomplete List of Disallowed Inputs in versions 0.0.1 - 1.23.0 and 2.0.0 - 2.4.0.
How to fix this
Upgrade the paragonie/sodium_compat library to the patch version.
