Summary

CVE-2026-81676 is a SQL injection vulnerability (CWE-89) in TOOOLS’ iSquad application, affecting the /ws/apitribuna/ultimosVideos endpoint. The limit_videos request parameter is concatenated directly into a MariaDB SQL query without sanitization or parameterization, allowing a remote, unauthenticated attacker to inject SQL syntax. The vulnerability is rated 8.8 (High) and requires no privileges or user interaction.

Technical details

  • Root cause: The limit_videos parameter passed to the /ws/apitribuna/ultimosVideos endpoint is directly concatenated into a MariaDB SQL query instead of being parameterized or sanitized.
  • Trigger conditions: An attacker sends a crafted HTTP request to the vulnerable endpoint with malicious SQL syntax in the limit_videos parameter.
  • Attack vector: Network-based, no authentication or user interaction required.
  • Impact: Injected SQL syntax can break the underlying query structure, produce database errors, and expose internal database error messages/stack traces that reveal backend implementation details; per the CVSS vector, confidentiality impact is high.

Affected software

  • TOOOLS iSquad — all versions prior to 22/07/2026 (July 22, 2026)

Severity

  • CVSS Score: 8.8 (High)
  • CVSS v4.0 Vector: AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:L/VA:N/SC:N/SI:N/SA:N
    (A CVSS v3.1 vector was not published for this CVE at the time of this writeup; the score and vector above reflect the officially published CVSS v4.0 metrics.)

Mitigation and recommended actions

  • Immediate: Upgrade to the TOOOLS iSquad build released on or after 22/07/2026, which includes the vendor’s fix for this endpoint. TOOOLS has stated the fix has been deployed across all production instances, with no end-user action required.
  • If unable to confirm patch status: Restrict or monitor access to the /ws/apitribuna/ultimosVideos endpoint, validate/sanitize the limit_videos parameter at a WAF or reverse-proxy layer, and review web server logs for anomalous SQL syntax in requests to this endpoint.

How IONIX’s External Exposure Management Platform Detects and Validates
Zero-Days to Shrink MTTR

1

Map your entire attack surface (continously)

IONIX uses multi-factor discovery methods, including DNS analysis, certificate mapping, metadata inspection, and more, to automatically map every internet-facing asset across your environment. This includes cloud instances, third-party platforms, shadow IT, and even forgotten infrastructure that traditional tools miss.

2

Monitor for new CVEs

Dozens of threat intel feeds using agentic technology are continuously analyzed to detect the appearance of proof-of-concept code, exploit kits, and indicators of active targeting. IONIX goes further by applying AI to proactively evaluate whether emerging vulnerabilities are likely to be exploited, even before PoCs go public.

3

Identify Potential External Exposures

Not all CVEs matter. IONIX filters vulnerabilities by asking attacker-centric questions: Can it be reached from the internet? Does it require authentication? Is it being exploited in the wild? This dramatically reduces noise and focuses teams on threats that can actually be weaponized.

4

Create Safe, Scalable Exploit Validations

IONIX transforms real-world PoCs into safe, non-intrusive test payloads that can be run in production environments without disruption. These simulations are precisely targeted to the systems that are vulnerable, ensuring rapid validation without unnecessary load.

5

Execute Exploit Validations

By combining context about software stack, versioning, exposure status, and reachability, IONIX ensures that only the right payloads are executed against the right assets, maximizing efficiency and minimizing risk.

6

Drive Fast and Actionable Remediation

Results are routed through integrations with ticketing, SOAR, and SIEM tools. Issues are written in plain language, bundled into remediation clusters, and prioritized based on asset criticality, exploitability, and blast radius. This shortens mean time to remediation (MTTR) and empowers teams to act with confidence.
