CVE-2022-42479: Missing Authorization in TemplateHouse Soledad – MEDIUM Severity Access Control Bypass

Technical summary

CVE-2022-42479 is a broken access control vulnerability (CWE-862) in TemplateHouse Soledad that fails to properly enforce authorization rules. The affected functionality does not validate whether the requesting user has sufficient privileges before allowing access. The attack requires valid authentication credentials but no special privileges—any logged-in user can trigger the unauthorized access. The CVSS 3.1 vector (AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N) indicates network-accessible exploitation with low attack complexity, resulting in confidentiality and integrity impact within the scope of the vulnerable service.

Business impact

This vulnerability creates an insider-risk exposure where legitimate users can escalate their access to restricted data or operations. In multi-tenant or role-based deployments of Soledad, attackers could exfiltrate sensitive information belonging to other users or organizations, or modify data they should not control. The ability for authenticated users to bypass authorization is particularly damaging in shared hosting or team collaboration scenarios, undermining the integrity of access governance and potentially violating compliance obligations around data segregation.

Affected systems

TemplateHouse Soledad versions from the earliest through 8.2.5 are affected. Organizations running any version at or below 8.2.5 should assess whether they have deployed this product and verify their current version.

Exploitability

The vulnerability is moderately exploitable. It requires valid authentication credentials to trigger, which limits the attack surface to users with legitimate accounts. However, no special privileges are needed—any authenticated user can exploit the flaw. Attack complexity is low, and the vulnerability is network-accessible without requiring user interaction. These factors make it a realistic insider threat and account-compromise scenario, though it is not wormable or exploitable by unauthenticated attackers.

Remediation

Organizations must upgrade TemplateHouse Soledad to a patched version beyond 8.2.5. Verify the availability of a fixed version from TemplateHouse and test thoroughly in a staging environment before deploying to production. In parallel, implement network segmentation and role-based access controls at the application layer to limit exposure. Monitor authentication logs and access patterns for unauthorized privilege escalation attempts.

Patch guidance

Contact TemplateHouse or check their security advisory to identify the patch version that resolves CVE-2022-42479. Verify the version number against the vendor advisory, as patch availability and timing may vary. Once a fixed version is confirmed, schedule a maintenance window and perform standard pre-deployment testing. If delays are expected, prioritize patching systems that handle the most sensitive data or serve the most critical users.

Detection guidance

Monitor Soledad access logs for evidence of cross-user or cross-organization data access by authenticated users whose roles should not permit such activity. Look for API calls or form submissions to restricted endpoints from accounts with limited privileges. Implement or enhance role-based access control (RBAC) logging to capture authorization failures and successes. Review user session logs for anomalous access patterns immediately after login, particularly for accounts that rarely access sensitive functions.

Why prioritize this

Although unranked by CISA in the Known Exploited Vulnerabilities catalog, this vulnerability merits prompt remediation due to its impact on data confidentiality and integrity in multi-user environments. The low attack complexity and lack of privilege requirements mean any legitimate user can exploit it, creating a persistent insider threat. Organizations hosting shared instances or handling regulated data should treat this as high-priority within their internal roadmap.

Risk score, explained

The CVSS 3.1 score of 5.4 (MEDIUM) reflects the need for valid authentication and the confidentiality/integrity impact but absence of availability impact. The score does not capture the organizational risk of unauthorized cross-user data access or the likelihood of insider exploitation in shared-hosting scenarios. Depending on deployment context—particularly the number of concurrent users and sensitivity of data—your organization may warrant higher internal prioritization.
