CVE-2026-22098: Information Disclosure Vulnerability

CVE-2026-22098 Overview

CVE-2026-22098 is an information disclosure vulnerability where sensitive data, including passwords and charging card unique identifiers (UIDs), is written to log files. The flaw is classified under [CWE-532] (Insertion of Sensitive Information into Log File). An unauthenticated network-based attacker who obtains access to the affected log files can retrieve credentials and card identifiers in cleartext. The Dutch Institute for Vulnerability Disclosure (DIVD) published the finding in report DIVD-2026-00001.

Critical Impact
Attackers who access exposed log files can harvest plaintext passwords and charging card UIDs, enabling account takeover and physical charging session abuse.

Affected Products

Technical Details for CVE-2026-22098

Vulnerability Analysis

The vulnerability results from the application writing sensitive fields directly into log records. Logged content includes authentication passwords and charging card UIDs used to authorize charging sessions. Log files are typically retained for troubleshooting and are accessible to administrators, technicians, and log aggregation services. When these logs are exposed over a network interface or shipped to less-privileged storage, the sensitive fields become recoverable by any party with read access.

The issue is a design flaw in the logging pipeline rather than a memory safety defect. No exploit code is required to weaponize the finding; reading the log file is sufficient to obtain the credentials.

Root Cause

The root cause is the absence of redaction or masking in the logging layer. Authentication and identification data are passed to log statements without filtering. [CWE-532] describes precisely this class of defect, where diagnostic verbosity outweighs data minimization controls.

Attack Vector

The attack vector is network-based and requires no privileges or user interaction. An attacker who can reach an exposed logging endpoint, retrieve backup archives, or query a centralized log store can read the plaintext values. Recovered passwords enable authenticated access to affected systems. Recovered charging card UIDs allow an adversary to clone card credentials and initiate charging sessions billed to a legitimate user.

No verified proof-of-concept code has been published. See DIVD-2026-00001 for coordinated disclosure details.

Detection Methods for CVE-2026-22098

Indicators of Compromise

Log entries containing password fields, RFID, or UID values in cleartext
Unexpected read access to log directories from non-administrative accounts
Egress transfers of log archives to external destinations
Replayed charging card UIDs appearing at unusual locations or times

Detection Strategies

Scan existing log stores with regular expressions for password-like tokens and UID patterns
Alert on file access to log paths by processes outside the logging service
Correlate authentication events with log-read events to identify credential harvesting
Baseline normal log volume and flag outbound transfers of log archives

Monitoring Recommendations

Ingest application and system logs into a centralized SIEM with access auditing enabled
Enforce integrity monitoring on log directories and rotation archives
Track service accounts with read access to log storage and review quarterly
Monitor charging session initiation for anomalous UID reuse or geographic impossibility

How to Mitigate CVE-2026-22098

Immediate Actions Required

Rotate all passwords that may have been written to affected log files
Reissue or revoke charging card UIDs known to appear in logs
Restrict log directory permissions to the minimum set of service accounts
Purge or sanitize historical log archives that contain exposed secrets

Patch Information

At the time of publication, no vendor patch information is listed in the NVD entry. Consult DIVD-2026-00001 for vendor coordination status and available fixes.

Workarounds

Configure logging frameworks to redact or hash sensitive fields before write
Lower log verbosity in production to exclude authentication payloads
Encrypt log files at rest and require authenticated access to retrieval endpoints
Segment log aggregation infrastructure from general network access

bash

# Example logging redaction pattern for a syslog forwarder
# Replace password= and uid= values before forwarding
rewrite r_redact_secrets {
    subst("(password|uid|rfid)=([^ &]+)", "\\1=[REDACTED]", value("MESSAGE") flags(global));
};
