Description
Vulnerability in Spring Spring Security. Applications that explicitly configure One-Time Token login with JdbcOneTimeTokenService are vulnerable to a Time-of-check Time-of-use (TOCTOU) race condition. This issue affects Spring Security: from 6.4.0 through 6.4.15, from 6.5.0 through 6.5.9, from 7.0.0 through 7.0.4.
Affected versions
Maven
| Package | Vulnerable | Fixed in |
|---|---|---|
| org.springframework.security:spring-security-core | >= 6.5.0, < 6.5.10 |
6.5.10 |
| org.springframework.security:spring-security-core | >= 7.0.3, < 7.0.5 |
7.0.5 |
| org.springframework.security:spring-security-core | >= 6.4.0, <= 6.4.13 |
No fix yet |
How to fix
Move to the fixed version or later with your package manager, update the lockfile, and run your tests. If the package only arrives through another dependency, upgrade that dependency first. If none of its releases pulls a fixed version yet, force the version with your package manager's override.

Weakness
CWE-367: Time-of-check Time-of-use (TOCTOU) Race Condition
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.
How to prevent it
- Implementation: The most basic advice for TOCTOU vulnerabilities is to not perform a check before the use. This does not resolve the underlying issue of the execution of a function on a resource whose state and identity cannot be assured, but it does help to limit the false sense of security given by the check.
- Implementation: When the file being altered is owned by the current user and group, set the effective gid and uid to that of the current user and group when executing this statement.
- Architecture and Design: Limit the interleaving of operations on files from multiple processes.
- Implementation, Architecture and Design: If you cannot perform operations atomically and you must share access to the resource between multiple processes or threads, then try to limit the amount of time (CPU cycles) between the check and use of the resource. This will not fix the problem, but it could make it more difficult for an attack to succeed.
- Implementation: Recheck the resource after the use call to verify that the action was taken appropriately.
- Architecture and Design: Ensure that some environmental locking mechanism can be used to protect resources effectively.
- Implementation: Ensure that locking occurs before the check, as opposed to afterwards, such that the resource, as checked, is the same as it is when in use.
