When the Identity Awareness blade is enabled with Browser-Based Authentication, an unauthenticated user may be able to read certain internal files on the Security Gateway.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidence
This is an unauthenticated file disclosure vulnerability in Check Point Security Gateways. When the Identity Awareness blade is enabled with Browser-Based Authentication, an unauthenticated attacker can read certain internal files on the gateway, potentially exposing sensitive system configuration or credential data.
MitigationDisable Browser-Based Authentication in the Identity Awareness blade configuration, or apply Check Point vendor patches when available. Restrict management interfaces to trusted networks as an interim control.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checks
Work through these to decide whether this CVE applies to you.
Confirm Check Point Security Gateway product
Identify the installed product is a Check Point Security Gateway (not a management console or other Check Point product). This vulnerability affects only Security Gateways, not SMS/MLM management appliances.
Affected if The product is NOT a Check Point Security Gateway (for example, if it is only a management server without gateway functionality, the specific vulnerability does not apply).
Verify Identity Awareness blade is enabled
Check if the Identity Awareness blade is active on the gateway. This is typically verified through the Check Point SmartConsole under the gateway properties, or via 'cpstat -f identity_server' command output showing identity awareness status.
Affected if Identity Awareness blade is NOT enabled - the vulnerability requires this blade to be active.
Confirm Browser-Based Authentication is enabled
Inspect the Identity Awareness configuration in SmartConsole (Gateway Properties > Identity Awareness) or via 'cpconfg' command to verify Browser-Based Authentication (BBA) is turned ON. BBA is the specific component that enables the unauthenticated file read.
Affected if Browser-Based Authentication is DISABLED in Identity Awareness settings - this is the required condition for exploitation.
Assess network exposure
Determine if the Security Gateway management interface or Identity Awareness ports are directly accessible from untrusted networks. The attacker needs network access to the gateway to trigger the file read.
Affected if The gateway is not directly accessible from unauthenticated network paths - exploitation requires the attacker to reach the gateway externally.
Your environment is affected if you run a Check Point Security Gateway with the Identity Awareness blade enabled and Browser-Based Authentication turned ON, and the gateway is network-accessible to unauthenticated attackers.

Disable Browser-Based Authentication in the Identity Awareness blade configuration, or apply Check Point vendor patches when available. Restrict management interfaces to trusted networks as an interim control.

CVE-2026-48133 is an unauthenticated file-read vulnerability in Check Point's Browser-Based Authentication (BBA) component, scoring CVSS 7.5. The vendor's description of accessible content as 'certain internal files' is the critical ambiguity you need to treat as a worst-case scenario until proven otherwise.
Start with this operational assumption: any unauthenticated file-read on a perimeter authentication portal should be treated as a potential credential harvester. BBA sits at the trust boundary—it's architecturally designed to receive unauthenticated browsers and route them toward authenticated sessions, which means it's intentionally excluded from normal security monitoring. You cannot apply standard WAF rules to a login portal without breaking authentication, and you cannot retroactively audit what the BBA process accessed during the exposure window. This makes the vulnerability's blast radius difficult to measure after the fact.
Three things demand immediate verification. First, determine whether your BBA URLs are internet-reachable or require prior authentication context—this determines your actual exposure. Second, check what filesystem scope the BBA process has; if it can read /home/admin/, /var/log/, or any credential stores, the 'certain files' language is materially understating risk. Third, compare this to prior Check Point web-component vulnerabilities—the pattern shows that 'certain files' disclosures consistently understate credential access when post-publication analysis confirms what was actually reachable.
The EPSS score of 0.0475 appears conservative given that BBA endpoints are commonly perimeter-facing. Prioritize patching regardless of EPSS-derived exploitation probability, because the credential disclosure scenario doesn't require active exploitation to be dangerous—it requires only that an attacker could have read the right file at the right time to pivot into the appliance's management interface.
