Adobe Commerce and Magento Improper Neutralization of Special Elements Used in a Template Engine Vulnerability
Vendor: Adobe Product: Commerce and Magento
Adobe Commerce and Magento Open Source contain an improper neutralization of special elements used in a template engine vulnerability that could allow an attacker to execute arbitrary code.
Each milestone comes from a different source, so gaps between them are gaps in what those sources publish, not evidence that nothing happened. EPSS history for this CVE holds 14 points from 2026-09-09, tracked daily from 2026-09-09; earlier points are weekly, which dates a spike to within a week. Peak probability 2.1% on 2026-09-09.

Articles from monitored vendor research blogs and security news feeds that specifically mention this CVE. Coverage begins when feed monitoring started; earlier articles are not indexed.
Coverage across public collections only: Nuclei and OpenVAS NVT (scan);
Snort and Suricata ET Open (network); Sigma and YARA (host/SIEM);
Metasploit, Exploit-DB and public GitHub repositories (exploit). Absence
here means nothing public was found, not that detection is impossible.
GitHub PoC repositories are collected automatically by
PoC-in-GitHub (CC0) and are not vetted:
some are fakes and some are malware. Treat them as evidence that code was
published, not as code to run.
