Security readout for executives and security teams
Plain-English summary
CVE-2026-24816 affects Datavane TIS before v4.3.0. The reported flaw is an infinite loop in a console action module, rated critical by CVSS 4.0. If your organization runs TIS, prioritize confirming the deployed version and applying the vendor patch or upgrade path.
Executive priority
High priority if Datavane TIS is in use, especially if the console is network-accessible. The CVSS score is critical, but public evidence is sparse and does not confirm real-world exploitation. Focus first on inventory, version confirmation, and upgrade planning.
Technical view
The CVE describes CWE-835 in tis-console ChangeDomainAction.java under com.qlangtech.tis.runtime.module.action. The record says TIS versions before v4.3.0 are affected. The CVSS 4.0 vector indicates network attack, low complexity, no privileges, no user interaction, and high confidentiality/integrity impacts, though the public detail is limited.
Likely exposure
Exposure is likely limited to organizations running Datavane TIS console versions before v4.3.0. Risk increases if the console is reachable from untrusted networks. The source data does not provide package identifiers, CPEs, or a complete version matrix.
Exploitation context
No CISA KEV listing is provided, and the cited sources do not state active exploitation. The CVSS vector suggests unauthenticated network reachability, but public sources do not describe exploitation mechanics. Treat internet-exposed or broadly reachable TIS consoles as higher priority for review.
Researcher notes
The public record is thin and contains a title mismatch referencing cookies while the technical description names an infinite loop. The strongest grounded facts are CWE-835, ChangeDomainAction.java, affected versions before v4.3.0, and patch reference PR 444. Avoid assuming exploitability beyond the CVSS vector.
Mitigation direction
- Identify all Datavane TIS deployments and their versions.
- Upgrade affected TIS instances to v4.3.0 or later if available.
- Review Datavane pull request 444 and related release notes.
- Restrict TIS console access to trusted networks while patching.
- Monitor vendor guidance for any additional remediation details.
Validation and detection
- Confirm whether each TIS instance is below v4.3.0.
- Verify the deployed build includes the ChangeDomainAction.java fix.
- Check whether TIS console is exposed to untrusted networks.
- Review application logs for repeated requests or resource exhaustion symptoms.
- Document compensating controls until all affected instances are remediated.

Loop with Unreachable Exit Condition ('Infinite Loop')
Loop with Unreachable Exit Condition ('Infinite Loop') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
