CVE-2026-81895 Details
In Concrete CMS before 9.5.3, the Document Library block stored the file-set identifiers submitted through fsID[] without validating them as integers, and when the block was configured with setMode set to any it concatenated each stored identifier directly into the file-set filter query instead of casting it or binding it as a parameter. An authenticated user permitted to add or edit a Document Library block could therefore persist SQL syntax in the block configuration (btDocumentLibrary.setIds), and that stored expression was executed every time the published page containing the block was rendered, producing stored, time-based blind SQL injection. The Concrete CMS security team gave this vulnerability a CVSS v4.0 score of 8.5 with vector CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:P/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N. Thanks Habib Allah for reporting.

Exploit prediction scoring system (EPSS) score for CVE-2026-81895
EPSS (Exploit Prediction Scoring System): EPSS predicts the likelihood that a vulnerability will be exploited in the wild. A higher percentage means a greater chance of an exploit occurring. The EPSS model produces a probability score between 0 and 1 (0 and 100%).
0.51 Probability of exploitation activity being observed over the next 30 days (43rd percentile)
CVSS score for CVE-2026-81895
CVSS (Common Vulnerability Scoring System): An open framework owned and managed by FIRST.Org, Inc. that assigns a numerical score from 0 to 10 to software vulnerabilities to indicate their severity.

Bitsight Data Discovery and Continuous Threat Scanning

Bitsight, the leading provider in Cyber Risk Management, introduced the next-generation internet scanner Bitsight Groma in May 2024. This technology continuously scans the entire internet to discover assets, collect asset attribution evidence, and identify an ever-growing set of security observations, such as vulnerabilities and misconfigurations. Groma’s scanning activities presently encompass:


  • 40 million-plus monitored organizations
  • 250 million-plus host names
  • 4 billion-plus routable IPv4 and IPv6 addresses

Greynoise’s recent study testifies the speed of Bitsight Groma.
