Adobe released security bulletin APSB26-05 on March 10, 2026, covering Adobe Commerce and Magento Open Source. Every supported release line got a patch on the same day.
What shipped
The patched versions are 2.4.8-p4, 2.4.7-p9, 2.4.6-p14, 2.4.5-p16 and 2.4.4-p17. Whichever line you are on, there is a version with your name on it — which is the point of the isolated security patch model Adobe moved to at the start of the year.
These are security fixes only. No feature changes, no breaking API modifications. That matters for the testing conversation: a security-only patch is a much smaller regression surface than a full quarterly bundle, and it should not need a full UAT cycle to go live.
What we would do about it
If you are on a supported line, take it. The reason merchants historically fell behind on security was that patches arrived welded to features they had not planned for, so the whole thing waited. That excuse is gone.
If you are on 2.4.4, read this one differently — the March patch is close to the end of the road for that line, and the upgrade conversation is the more useful one to have.
We apply these for the clients we look after as a matter of course. If you are not sure whether yours went on, that is a five-minute question and worth asking.
