CVE-2020-8226

20
FAUCET Score

CVE-2020-8226 is a Server-Side Request Forgery (SSRF) vulnerability affecting phpBB versions prior to 3.2.10 and 3.3.1, stemming from an insecure remote image dimensions check. This medium-severity vulnerability (CVSS 5.8) allows an unauthenticated attacker to initiate requests from the server, potentially leading to information disclosure (C:L) without direct impact on integrity or availability. While no public exploits, Metasploit modules, or Nuclei templates are available, and there is no evidence of active exploitation or significant community discussion, organizations using affected phpBB versions should prioritize patching to mitigate this risk.
