  • Oct 9, 2026A component loading mechanism in openPDC and openHistorian will construct and run any specified type, which may be an invalid component to load.CVE-2026-104629 · Other software · Grid Protection Alliance · reported by ics-cert@hq.dhs.govHigh 7.7

    A component loading mechanism in openPDC and openHistorian will construct and run any specified type, which may be an invalid component to load. An attacker with an authenticated user account and the ability to place a file on the host filesystem can use this to run arbitrary constructor code, and this code runs with the privileges of the affected service account.

  • Oct 9, 2026A Modbus connection feature on openPDC accepts a caller-specified destination address and port with no restriction on which internal hosts may be targeted.CVE-2026-101022 · Other software · Grid Protection Alliance · reported by ics-cert@hq.dhs.govMedium 5.3

    A Modbus connection feature on openPDC accepts a caller-specified destination address and port with no restriction on which internal hosts may be targeted. An authenticated user can attempt connections to arbitrary internal network destinations, revealing which destinations are reachable. With repeated attempts, an attacker may be able to map the internal network.

  • Oct 9, 2026A service console interface on openPDC and openHistorian deserializes a client-supplied data structure.CVE-2026-100730 · Other software · Grid Protection Alliance · reported by ics-cert@hq.dhs.govCritical 9.3

    A service console interface on openPDC and openHistorian deserializes a client-supplied data structure. On systems using Windows Authentication, an attacker must already be authenticated to reach this function; on systems without Windows Authentication, this is reachable by an unauthenticated network attacker. This allows an attacker to trigger deserialization of an arbitrary object graph, which could allow remote code execution under the privileges of the affected service account.

Where this comes from: the exploited list is CISA’s Known Exploited Vulnerabilities catalog. Everything else is the whole National Vulnerability Database, where each record is published by the team that found the bug (Wordfence, Patchstack, WPScan, the vendors themselves and others); we show who. Exploit odds are FIRST’s EPSS, updated daily. Titles and categories are ours, so check the linked record before acting on a detail. For a write-up of the big ones, see our advisories. Every vendor, and every WordPress plugin and theme with a recorded flaw, also has its own page. All of it is free to reuse as JSON, CSV or RSS.
