A Regular Expression Denial of Service (ReDOS) vulnerability was discovered in that-value v0.1.3 when validating crafted invalid emails.
The product uses a regular expression with an inefficient, possibly exponential worst-case computational complexity that consumes excessive CPU cycles.
| Name | Vendor | Start Version | End Version |
|---|---|---|---|
| That-value | That-value_project | 0.1.3 (including) | 0.1.3 (including) |
Attackers can create crafted inputs that
intentionally cause the regular expression to use
excessive backtracking in a way that causes the CPU
consumption to spike.
