CVE-2026-104055 Vulnerability Summary

CVE-2026-104055: The postgresql-operator charm runs a Prometheus postgres_exporter to collect database metrics using a dedicated "monitoring" PostgreSQL user. On database connection errors, the exporter writes the monitoring user's password in cleartext to its logs. Any actor able to read those logs can recover the password, which grants read-only pg_monitor access to PostgreSQL. This is fixed in the dev track (14/edge) in revisions 1189 (arm64) and 1190 (amd64), and in the stable track (14/stable) in revisions 1216 (arm64) and 1217 (amd64).

Assessing the Risk of CVE-2026-104055

Access Complexity Graph

The exploitability of CVE-2026-104055 depends on two key factors: attack complexity (the level of effort required to execute an exploit) and privileges required (the access level an attacker needs).

Exploitability Analysis for CVE-2026-104055

No exploitability data is available for CVE-2026-104055.

Understanding AC and PR

A lower complexity and fewer privilege requirements make exploitation easier. Security teams should evaluate these aspects to determine the urgency of mitigation strategies, such as patch management and access control policies.

Attack Complexity (AC) measures the difficulty in executing an exploit. A high AC means that specific conditions must be met, making an attack more challenging, while a low AC means the vulnerability can be exploited with minimal effort.

Privileges Required (PR) determine the level of system access necessary for an attack. Vulnerabilities requiring no privileges are more accessible to attackers, whereas high privilege requirements limit exploitation to authorized users with elevated access.

CVSS Score Breakdown Chart

Above is the CVSS Sub-score Breakdown for CVE-2026-104055, illustrating how Base, Impact, and Exploitability factors combine to form the overall severity rating. A higher sub-score typically indicates a more severe or easier-to-exploit vulnerability.

CIA Impact Analysis

Below is the Impact Analysis for CVE-2026-104055, showing how Confidentiality, Integrity, and Availability might be affected if the vulnerability is exploited. Higher values usually signal greater potential damage.

  • Confidentiality: None
    CVE-2026-104055 does not compromise confidentiality.
  • Integrity: None
    CVE-2026-104055 does not impact data integrity.
  • Availability: None
    CVE-2026-104055 does not affect system availability.

CWE-532

CAPEC Common Attack Pattern Enumeration and Classification

  • Fuzzing for application mapping CAPEC-215 An attacker sends random, malformed, or otherwise unexpected messages to a target application and observes the application's log or error messages returned. The attacker does not initially know how a target will respond to individual messages but by attempting a large number of message variants they may find a variant that trigger's desired behavior. In this attack, the purpose of the fuzzing is to observe the application's log and error messages, although fuzzing a target can also sometimes cause the target to enter an unstable state, causing a crash.
