Adobe Commerce versions 2.4.9-alpha1, 2.4.8-p1, 2.4.7-p6, 2.4.6-p11, 2.4.5-p13, 2.4.4-p14 and earlier are affected by a Time-of-check Time-of-use (TOCTOU) Race Condition vulnerability that could result in a security feature bypass. An attacker could exploit this vulnerability by manipulating the timing between the check of a resources state and its use, allowing unauthorized write access. Exploitation of this issue does not require user interaction.
The product checks the state of a resource before using that resource, but the resource’s state can change between the check and the use in a way that invalidates the results of the check. This can cause the product to perform invalid actions when the resource is in an unexpected state.
