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 Gumloop?
Gumloop 13.6 gives admins one set of rules for every tool an agent touches.
Gumloop ships a numbered release every few days. 13.0 rebuilt the agent harness, 13.3 published agents to Okta, 13.4 cut agent tokens per step by about 40% and 13.5 added live multi-user tasks. 13.6 extends admin guardrails from connectors to every tool, redacts card numbers and passwords before models see them, warns when agent instructions contain credentials, adds browser allow and block lists and domain-restricted API keys, and introduces Workforce Atlas, a board of every agent and skill in the organization.

AcyMailing
2.5MKT AUTO
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.
Gumloop
6.3MKT AUTO
Gumloop 13.6 gives admins one set of rules for every tool an agent touches.
◆ Current state
Gumloop ships a numbered release every few days. 13.0 rebuilt the agent harness, 13.3 published agents to Okta, 13.4 cut agent tokens per step by about 40% and 13.5 added live multi-user tasks. 13.6 extends admin guardrails from connectors to every tool, redacts card numbers and passwords before models see them, warns when agent instructions contain credentials, adds browser allow and block lists and domain-restricted API keys, and introduces Workforce Atlas, a board of every agent and skill in the organization.
◆ Where it's heading
Since 13.2 the releases have moved from what agents can do toward how a company controls them. 13.6 is the broadest step yet: approval rules, data redaction and secret handling now cover all agent activity, which is what security teams ask for before a wide rollout.
◆ Prediction
Expect Workforce Atlas to leave beta with more tags and reporting, and more enterprise controls such as audit exports built on the new guardrail records.
