DescriptionCVE.org

CWE‑522: Insufficiently Protected Credentials in web services in Progress Sitefinity version from 14.0.7700 to 14.4.8152, and 15.0.8200 to 15.0.8234, and 15.1.8300 to 15.1.8335, 15.2.8400 to 15.2.8441, 15.3.8500 to 15.3.8531, and 15.4.8600 to 15.4.8630 allows a remote unauthenticated attacker to obtain plain-text credentials used connect to Sitefinity Insight service. Successful exploitation requires active integration with Sitefinity Insight and non-default site configuration.

AnalysisAI

Credential disclosure in Progress Sitefinity 14.0.7700-15.4.8630 allows remote unauthenticated attackers to retrieve plaintext credentials used to connect to the Sitefinity Insight analytics service. The CVSS 10.0 score reflects network-reachable, no-auth, no-interaction exploitation with cross-scope impact, though exploitation is gated on the site having active Sitefinity Insight integration and a non-default configuration. No public exploit identified at time of analysis and the vendor (Progress) is the sole reporting source via a May 2026 advisory.

Technical ContextAI

Progress Sitefinity is a .NET-based digital experience and web content management platform commonly deployed for enterprise marketing sites. The vulnerability sits in Sitefinity's web services layer that handles configuration for the Sitefinity Insight integration - a separate Progress SaaS analytics/personalization product that ingests behavioral data from Sitefinity sites. The root cause maps to CWE-522 (Insufficiently Protected Credentials): the Insight connection credentials are exposed in plain text through a web service path reachable without authentication, rather than being protected behind admin-only endpoints or stored/transmitted only in protected form. The advisory does not specify the exact endpoint, but the CVSS Scope:Changed metric indicates the bug in Sitefinity yields impact against a separate security authority - consistent with stealing credentials that authenticate the site to the downstream Insight tenant.

RemediationAI

Patch available per vendor advisory - apply the fixed builds published by Progress in the May 2026 Sitefinity security advisory (https://community.progress.com/s/article/Sitefinity-Security-Advisory-for-Addressing-Security-Vulnerabilities-CVE-2026-7312-CVE-2026-7198-CVE-2026-7195-CVE-2026-7201-CVE-2026-7313-May-2026); exact post-fix version numbers per branch are not enumerated in the available data and must be confirmed against that advisory. As an interim compensating control while patching, customers running Sitefinity Insight integration should rotate the Insight API credentials immediately after patching (assume them compromised), disable the Insight integration if it is not in active use to eliminate the exposed credential, and place authentication or network-layer restrictions in front of Sitefinity's web service endpoints - for example by IP-allowlisting administrative paths at the reverse proxy or WAF - accepting that overly broad blocking can also break legitimate Insight callbacks and editor tooling. Reverting to the default site configuration, where compatible, also avoids the vulnerable code path per the vendor's description but may regress site behavior that depended on the customization.
