Summary
Conversion of empty strings to null allows disguising DPA reports as genuine self-deletion reports.
Details
Creating a DPA report about another user and leaving the evidence field empty causes that report to look like the reported user self-requested deletion of their data. Ingenuine report is not distinguishable from a genuine one.
This can be prevented by disabling convertEmptyStringsToNull in the middleware, or by validating evidence in Http/Controllers/DPAController::store() to not be empty.
PoC
New DPA report -> Select "...someone who I suspect is under the age of 13" for the "The above username is..." field -> Add nothing to the "Evidence" field -> Submit
Impact
Potential unauthorized deletion of any arbitrary user's data both in the current system (TSPortal) and subsequent systems if actioned.
CVE-2026-29788 has a CVSS score of 7.5 (High). The vector is network-reachable, no privileges required, and no user interaction. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. A fixed version is available (30); upgrading removes the vulnerable code path.

Kodem intelligence
Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.
Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter. Kodem's runtime-powered SCA identifies whether this CVE is reachable in your applications.
Remediation advice
Kodem Kai can prioritize this vulnerability in your dependency tree and generate a fix recommendation.
Frequently Asked Questions
- What is CVE-2026-29788? CVE-2026-29788 is a high-severity security vulnerability in miraheze/ts-portal (composer), affecting versions <= 29. It is fixed in 30.
- How severe is CVE-2026-29788? CVE-2026-29788 has a CVSS score of 7.5 (High). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.
- Which versions of miraheze/ts-portal are affected by CVE-2026-29788? miraheze/ts-portal (composer) versions <= 29 is affected.
- Is there a fix for CVE-2026-29788? Yes. CVE-2026-29788 is fixed in 30. Upgrade to this version or later.
- Is CVE-2026-29788 exploitable, and should I be worried? Whether CVE-2026-29788 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

- What actually determines whether CVE-2026-29788 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
- How do I fix CVE-2026-29788? Upgrade
miraheze/ts-portalto 30 or later.
