- Exploitation
- No exploitation in the wild and no public exploit is recorded for the CVEs named.
NCSC-NL published an advisory for an authentication bypass vulnerability (CVE-2026-83527, CVSSv3 8.1) affecting Ivanti Sentry versions prior to R10.8.2, R10.7.3, and R10.6.4. The flaw is classified as authentication bypass using an alternate path or channel, allowing unauthenticated remote attackers to obtain administrative access to affected systems, potentially resulting in full unauthorized control over administrative functions.
Ivanti has released updated versions that remediate the vulnerability. No evidence of active in-the-wild exploitation is mentioned in the advisory. Defenders running Ivanti Sentry should prioritize patching to the fixed releases (R10.8.2, R10.7.3, R10.6.4 or later) and review administrative access logs for anomalous or unauthorized administrative activity as a precautionary detection measure, given the criticality of admin-level compromise on this platform.

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.
