Server-Side Request Forgery and Input Validation and Logic
33 CVEs · 1 exploited
33 CVEs name a weakness of both Server-Side Request Forgery and Input Validation and Logic, fewer than chance alone would give (about 44). The pairing most often behind it is CWE-918 (Server-Side Request Forgery) with CWE-184 (Incomplete List of Disallowed Inputs), in 12 CVEs.
Every dot is a CVE whose record names a weakness from both classes, neither being the other's parent in the CWE hierarchy. The named ones come first: exploited in the wild, then those with a public check, then the likeliest to be.
- CVEs that carry a weakness of both
- 33
- Chance alone would give
- about 44
- So they are recorded together
- less often than chance (0.8×)
A CVE counts when its record names a weakness from each class, neither being the other's parent. It says the two kinds of flaw are recorded together in one vulnerability more or less often than chance: not that one causes the other, and it follows how the people who file CVEs choose CWEs.
How this is weighed, and the sources
Chance is what the two classes' shares of all CVEs that carry weaknesses of two or more classes would give if weaknesses paired at random. A line is drawn on the dial from 25 CVEs and 1.15 times chance. Weaknesses are the CWEs the CVE List and NVD record; exploitation is CISA KEV, likelihood is EPSS.
