AcyMailing vs OpenEMM: at a glance
What is AcyMailing?
AcyMailing 11.1.2 closes holes that let strangers read or unsubscribe any subscriber.
AcyMailing is a Joomla and WordPress email marketing extension. Release 11.1.2 is a security update: it fixes an unauthenticated leak of subscriber data including the subscriber key, anonymous unsubscribing of any known address, logged-in users changing other people's subscriptions, unchecked post-subscription redirects and campaign archive pages opening without permission. It follows 11.1's privacy work, a per-subscriber tracking switch and fixed one-click unsubscribe.
What is OpenEMM?
OpenEMM 26.11 reaches GA eight days after its beta.
OpenEMM released 26.11.169 as the general-availability build of the 26.11 line on November 12, eight days after the 26.11.136 beta. The notes list only the frontend version. The 26.05 line it replaces reached GA in July and has had only frontend builds since.

AcyMailing 11.1.2 closes holes that let strangers read or unsubscribe any subscriber.
◆ Current state
AcyMailing is a Joomla and WordPress email marketing extension. Release 11.1.2 is a security update: it fixes an unauthenticated leak of subscriber data including the subscriber key, anonymous unsubscribing of any known address, logged-in users changing other people's subscriptions, unchecked post-subscription redirects and campaign archive pages opening without permission. It follows 11.1's privacy work, a per-subscriber tracking switch and fixed one-click unsubscribe.
◆ Where it's heading
Since the 11.0 security rework in July, AcyMailing's releases alternate between privacy features and fixes for flaws in how subscriber actions are authorized. 11.1.2 shows the 11.0 rework left gaps in the subscription paths, now patched with ownership checks and security tokens.
◆ Prediction
A security advisory with full details is promised once users have had time to update, and further 11.1.x patches are likely as those details invite scrutiny of related code paths.
OpenEMM
5.0MKT AUTO
OpenEMM 26.11 reaches GA eight days after its beta.
◆ Current state
OpenEMM released 26.11.169 as the general-availability build of the 26.11 line on November 12, eight days after the 26.11.136 beta. The notes list only the frontend version. The 26.05 line it replaces reached GA in July and has had only frontend builds since.
◆ Where it's heading
OpenEMM keeps its twice-yearly cycle: a beta, a GA, then months of frontend-only maintenance builds. The notes never say what a line changes, so the cadence is the only visible signal.
◆ Prediction
Expect frontend-only 26.11 maintenance builds over the coming months; the entries give no hint of feature content.
