What to check
- Applies to
- The 2 CVEs named below. Whether you run an affected version is not assessed: check the versions the source lists.
- Exploitation
- CISA lists CVE-2026-114713 and CVE-2026-123039 as exploited in the wild.
CISA has added two vulnerabilities to its Known Exploited Vulnerabilities (KEV) Catalog based on confirmed evidence of active exploitation: CVE-2026-114713, an improper neutralization of delimiters vulnerability in UnrealIRCd, and CVE-2026-123039, an incorrect permission assignment for a critical resource vulnerability affecting multiple Check Point products. Neither the specific exploitation details nor threat actor attribution were disclosed in this bulletin.
Under Binding Operational Directive (BOD) 26-04, FCEB agencies are required to prioritize remediation of KEV-listed vulnerabilities that grant total control of an asset post-exploitation when exposed to the public internet, and to check for prior compromise before patching. While the directive is binding only on federal civilian agencies, CISA recommends all organizations using UnrealIRCd or the affected Check Point products treat these as high-priority patches and assess whether systems were compromised prior to remediation.
Defenders running UnrealIRCd or any Check Point product should consult vendor advisories for patched versions and apply updates immediately, particularly on internet-facing deployments. Given the nature of the vulnerability classes—delimiter handling issues and permission assignment flaws on critical resources—organizations should also review logs for signs of unauthorized access or privilege escalation predating patch application.

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 16,572 reports from 147 sources, 724 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.
