CVE-2025-46388: Information Disclosure Vulnerability

CVE-2025-46388 Overview

CVE-2025-46388 is an information disclosure vulnerability categorized under [CWE-200] Exposure of Sensitive Information to an Unauthorized Actor. The flaw allows an authenticated network attacker with low privileges to access data intended to be protected from that actor. No user interaction is required to exploit the issue. The vulnerability affects confidentiality only. Integrity and availability of the target system remain intact. The advisory was tracked through the Israeli Government CVE Advisories program.

Critical Impact
An authenticated attacker with low privileges can retrieve sensitive information over the network without user interaction, undermining data confidentiality boundaries.

Technical Details for CVE-2025-46388

Vulnerability Analysis

The vulnerability stems from insufficient access controls that expose sensitive information to actors who should not receive it. An attacker who already holds a low-privilege account on the target system can query or interact with an interface that returns data belonging to another user, tenant, or privilege boundary. The exposure is limited to confidentiality. The attacker cannot alter data or disrupt service through this issue alone. However, disclosed information can enable follow-on attacks, including credential theft, reconnaissance of internal architecture, or privilege escalation when combined with other flaws.

Root Cause

The root cause is improper authorization or filtering logic in a component that returns information to authenticated clients. Under [CWE-200], the affected code path fails to verify that the requesting principal is entitled to the data returned. This class of weakness commonly arises when developers rely on client-side filtering, obscure identifiers, or trust in session context without server-side enforcement.

Attack Vector

Exploitation occurs over the network against a service that accepts authenticated requests. The attacker uses valid low-privilege credentials to send crafted requests that induce the server to return data outside the attacker's authorization scope. No social engineering or user interaction is required. The specific request structure depends on the affected product, which is not disclosed in the current NVD entry.

See the Israeli Government CVE Advisories for product-specific technical details.

Detection Methods for CVE-2025-46388

Indicators of Compromise

Repeated authenticated requests to data-access endpoints originating from a single low-privilege account
Application logs showing successful responses to requests referencing resource identifiers outside the requester's normal scope
Unusual volume of read operations tied to service accounts or recently created low-privilege users

Detection Strategies

Baseline normal per-user data access patterns and alert on deviations in request volume, endpoint diversity, or object identifiers accessed
Instrument authorization checks with structured logging so denied and allowed access decisions can be correlated across sessions
Correlate authentication events with data-access telemetry to detect credential misuse consistent with information disclosure attempts

Monitoring Recommendations

Forward application, authentication, and API gateway logs to a centralized analytics platform for retention and query
Enable alerting on enumeration patterns such as sequential identifier access or bulk export operations by low-privilege roles
Review vendor advisories through the Israeli Government CVE Advisories portal for indicators tied to the affected product

How to Mitigate CVE-2025-46388

Immediate Actions Required

Identify affected assets by cross-referencing the advisory once vendor details are published
Restrict network exposure of the vulnerable service to trusted management networks where possible
Audit low-privilege accounts and disable those that are unused or unnecessary
Rotate credentials for accounts that may have accessed exposed data

Patch Information

A specific vendor patch identifier is not listed in the current NVD entry. Organizations should monitor the Israeli Government CVE Advisories listing for vendor updates and apply security fixes as they are released. Test patches in a staging environment before deploying to production systems handling sensitive data.

Workarounds

Enforce least-privilege role assignments so accounts hold only the permissions required for their function
Place the affected service behind an authenticated reverse proxy that applies additional authorization checks
Enable request-level logging and rate limiting to constrain enumeration by any single account
Segment sensitive data stores from general-purpose application tiers to reduce the blast radius of any single account compromise
