What to check
- Applies to
- The 3 CVEs named below. Whether you run an affected version is not assessed: check the versions the source lists.
- Exploitation
- CISA lists CVE-2026-48908, CVE-2026-55255, and CVE-2026-56290 as exploited in the wild.
CISA has expanded its Known Exploited Vulnerabilities (KEV) Catalog with three new entries based on confirmed evidence of active exploitation: a file upload vulnerability in JoomShaper SP Page Builder, an authorization bypass in Langflow tied to user-controlled key handling, and an improper access control flaw in Joomlack Page Builder. These vulnerability classes are commonly abused attack vectors and pose elevated risk to internet-facing assets across federal and private-sector environments.
Under Binding Operational Directive (BOD) 26-04, Federal Civilian Executive Branch agencies are required to prioritize remediation of KEV-listed vulnerabilities on publicly exposed assets, particularly those enabling full asset compromise, and to verify whether systems were compromised prior to patching. While the directive is binding only on FCEB agencies, CISA recommends all organizations adopt similar risk-based patching practices for these three CVEs and other KEV entries.
No specific threat actor, malware, or campaign has been attributed to the exploitation of these vulnerabilities in this alert; the notice serves primarily as a remediation directive rather than a detailed technical advisory.

Free public brief. Slack alerts on the vendors you run come with the paid plans, and a new account gets three days of them, no card.
What this brief leaves out
This page is the free tier: the write-up, the severity, the names. In the app the same report carries live profiles of the CVEs it names. The paid plans add the security research and news reporting the free tier leaves out.
It sits in a corpus of 16,436 reports from 149 sources, 661 of them written in the last seven days, and it grows through the day.
A new account starts with three days of all of it, no card, then keeps the government and CERT reporting free. Slack alerts are a paid-plan feature: name the vendors you run and Slack hears about the reports that touch them, not the rest of the week's. Nothing is charged unless you subscribe.
