City-Forum campaign steals data from misconfigured Salesforce and ServiceNow portals

Researchers at Reco detailed a long-running data-theft campaign they call City-Forum that has been quietly stealing records from Salesforce and ServiceNow customer portals since at least March 2025. Rather than exploiting a platform vulnerability, the attacker uses custom tooling to pull data that organizations mistakenly exposed to anonymous guest users through overly permissive sharing rules and portal settings. It targets Salesforce Experience Cloud sites and a poorly documented ServiceNow portal search endpoint, hitting telecoms, banks, software vendors, security firms, and public-sector portals worldwide. All activity traces to a single server, and one victim alone saw over half a million data enumeration requests.

Check
Audit guest-user permissions and sharing rules on Salesforce Experience Cloud and ServiceNow portals, disable guest access to public APIs and unused self-registration, and confirm sensitive data is not reachable anonymously.
Affected
Organizations exposing Salesforce or ServiceNow portals with overly permissive guest access; attackers can enumerate and steal accounts, contacts, cases, and other records without any credentials or platform exploit.
Fix
Apply least privilege to guest profiles, remove broad API permissions, monitor the portal search and Aura endpoints for automated enumeration, and treat anonymously reachable data as effectively public until proven otherwise.

Critical ServiceNow AI Platform flaw now exploited in attacks

A critical flaw in the ServiceNow AI Platform is now being exploited in attacks. ServiceNow disclosed CVE-2026-6875 on July 13 in advisory KB3137947, describing it as a sandbox escape that lets an attacker bypass intended platform restrictions and execute code, and noting that exploitation does not require authentication. The AI Platform underpins much of the company's IT service management and workflow tooling, and the flaw affects both hosted and self-hosted deployments. ServiceNow deployed fixes to its hosted instances and released updates for self-hosted customers. Because these instances commonly connect to identity systems, cloud services, and endpoint management tools, a compromised one is a strong pivot point.

Check
Confirm your ServiceNow family release includes the fix for this flaw, prioritize self-hosted and internet-reachable instances, and review platform and AI feature logs for anomalous activity.
Affected
Organizations running unpatched ServiceNow AI Platform deployments (CVE-2026-6875), hosted or self-hosted; unauthenticated attackers can escape the sandbox and run code on a platform wired into identity, cloud, and endpoint systems.
Fix
Apply the fixed release for your family, verify hosted instances received the update, restrict instance exposure, and rotate integration tokens if compromise is suspected, while monitoring for unusual record changes.

ServiceNow API flaw let attackers query customer instance data

ServiceNow has quietly told affected customers that attackers exploited an unauthenticated flaw in one of its API endpoints to pull data from hosted customer instances. The company applied a fix to hosted instances on June 5 that restricts the endpoint to authenticated users, and confirmed attackers had successfully queried customer instance tables, though it did not say what data was taken. ServiceNow instances routinely hold sensitive material such as IT support tickets, employee records, asset inventories, and internal documentation, and support tickets in particular often contain credentials, API tokens, and secrets shared during troubleshooting. ServiceNow has opened support cases with the customers it believes were impacted.

Check
Check your ServiceNow support portal for a case opened by ServiceNow about this incident, and review instance access and API logs for unexpected unauthenticated queries before June 5.
Affected
Organizations running hosted ServiceNow instances whose data could be reached through the vulnerable unauthenticated API endpoint before the June 5 fix, especially those storing secrets in support tickets.
Fix
Confirm the June 5 fix applied to your instance, rotate any credentials, API tokens, or secrets that appeared in support tickets, and tighten access controls and logging on the instance.
