PHP2Shell Security Flaws Now Successfully Exploited
Comments on “PHP2Shell Security Flaws Now Successfully Exploited”
Claim-checked. Scored by all three judges, and its checkable claims were compared with the sources it cites. How far stories are checked
Researchers report that the PHP2Shell flaws (CVE-2026-109618 and CVE-2026-109619) have been exploited successfully in the wild, days after patches shipped and after earlier attempts failed. Adel Karimi's honeypot logged remote code execution with memory disclosure against Apache mod_php on PHP 8.4.26, and Marcus Hutchins backed the analysis. Most of these details were not independently verified. Karimi notes the evidence covers a deliberately favorable single-worker setup, not general reliability. Teams running mod_php should confirm the patches are applied.
Why it ranked
No. 14 of 124 with a score of 0.69. The panel rated it highest on reader interest (0.81) and practical relevance (0.80), lowest on new information (0.48). The judges disagreed most on new information (spread 0.59), so the story is marked contested.
Every answer behind this is in the table under Score.

Karimi said the evidence demonstrates the chain only on a single-worker mod_php profile and does not measure exploit reliability on other worker counts, PHP builds, or applications.
