• CVE-2026-40315: 0.30% estimated exploitation activity in the next 30 days; percentile 22.40 (FIRST EPSS, 2026-11-03). This is a model estimate, not proof of exploitation or customer exposure.

As published by the source; long descriptions are shortened.

Summary The tableprefix configuration value is directly used to construct SQL table identifiers without validation. If an attacker controls this value, they can manipulate SQL query structure, leading to unauthorized data access (e.g., reading internal SQLite tables such as sqlitemaster) and tampering with query results. --- Details This allows attackers to inject arbitrary SQL fragments into table identifiers, effectively altering query execution. This occurs because tableprefix is passed from configuration (fromyaml / fromdict) into SQLiteConversationStore and directly concatenated into SQL queries via f-strings: This value is then used in queries such as: Since SQL identifiers cannot be safely parameterized and are not validated, attacker-controlled input can modify SQL query structure. The vulnerability originates from configuration input and propagates through the following flow: Source: config.py (fromyaml / fromdict) accepts external configuration input Propagation: factory.py…

# Patch Next advisory brief: CVE-2026-40315

Advisory: PraisonAI: SQLiteConversationStore didn't validate table_prefix when constructing SQL queries
IDs: CVE-2026-40315, GHSA-x783-xp3g-mqhp
Record: https://patchnext.com/advisories/cve-2026-40315 (revision 3, source checked 26 Oct 2026, 13:40 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 6.9)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: praisonai 4.5.133. A vendor fix does not mean a deployment is fixed.

## Affected components
- PyPI praisonai: affected < 4.5.133; fixed in 4.5.133

## Suggested inspection (read-only)
- `python -m pip show praisonai`: prints the installed version. Run with the environment that serves production active.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on praisonai.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.

## Sources
- Verified: https://osv.dev/vulnerability/GHSA-x783-xp3g-mqhp (OSV record GHSA-x783-xp3g-mqhp lists affected ranges: PyPI praisonai >=0 <4.5.133 (fixed))
- Verified: https://github.com/advisories/GHSA-x783-xp3g-mqhp (GitHub-reviewed advisory GHSA-x783-xp3g-mqhp lists affected ranges: PyPI praisonai >=0 <4.5.133)
