PatchSiren cyber security CVE debrief
CVE-2026-82028 absmach CVE debrief
A SQL injection vulnerability exists in Magistrala before version 1.0.0, specifically in the timescale-reader and postgres-reader HTTP API services. This allows authenticated attackers to inject arbitrary SQL by manipulating the format query parameter, which is directly interpolated into the FROM clause without proper parameterization or quoting. The vulnerability can be exploited by attackers with self-registered accounts, enabling them to perform cross-tenant database reads, extract password hashes from pg_shadow, read and write arbitrary files, and execute arbitrary code as the postgres OS user by loading malicious shared objects. All injected SQL executes with superuser privileges due to the default PostgreSQL role configuration.

Who should care
Defenders responsible for Magistrala deployments, especially those with exposed instances accessible to authenticated users, should assess their exposure and prioritize mitigation. This includes reviewing current versions, applying patches, and monitoring for suspicious activity.
Why it matters
CVE-2026-82028 is a SQL injection vulnerability in Magistrala before version 1.0.0 that allows authenticated attackers to inject arbitrary SQL, potentially leading to severe consequences including data breaches, system compromise, and unauthorized access. Defenders should prioritize patching or mitigating this vulnerability, especially in exposed environments.
- Potential for cross-tenant database reads, allowing unauthorized access to sensitive data.
- Possible extraction of pg_shadow password hashes, which could be used for further exploitation.
- Ability for attackers to read and write arbitrary files, potentially leading to data breaches or system compromise.
- Execution of arbitrary code as the postgres OS user, which could result in full system compromise.
Technical summary
The SQL injection vulnerability in Magistrala before version 1.0.0 is caused by the direct interpolation of the format query parameter into the FROM clause of SQL queries without proper parameterization or quoting. This allows authenticated attackers to inject arbitrary SQL, potentially leading to cross-tenant database reads, extraction of pg_shadow password hashes, reading and writing of arbitrary files, and execution of arbitrary code as the postgres OS user.
Defensive priority
Defenders should prioritize patching or mitigating this vulnerability, especially in environments where Magistrala is exposed to authenticated users. This involves assessing the current version of Magistrala in use, verifying exposure to the vulnerable components, and applying patches or workarounds as available.
Recommended defensive actions
- Assess the current version of Magistrala in use and verify exposure to the vulnerable components.
- Apply patches or workarounds as available to mitigate the SQL injection vulnerability.
- Monitor for suspicious activity, especially in environments where Magistrala is exposed to authenticated users.
- Consider implementing additional security measures, such as input validation and SQL query parameterization.
- Review compensating controls for exposed systems while remediation is scheduled and verified.
- Check relevant monitoring, detection, and logs for exposed assets that need extra review.
- Track exceptions, retest remediated assets, and close the item only after evidence is documented.
