CVE-2026-85062 Vulnerability Summary

CVE-2026-85062: Colord is a tiny yet powerful tool for high-performance color manipulations and conversions. Prior to 2.9.4, synchronous CSS color string matchers in src/colorModels/rgbString.ts, src/colorModels/hslString.ts, src/colorModels/hwbString.ts, src/colorModels/lchString.ts, and src/colorModels/cmykString.ts use the ambiguous numeric regular expression ([+-]?\d*.?\d+), allowing the same digits to be divided between overlapping quantifiers in quadratically many ways when malformed input is rejected. An attacker who can supply an unbounded color string to colord(), getFormat(), isEqual(), mix(), or contrast(), including through a request body, JSON field, or uploaded stylesheet, can block the processing thread with a multi-kilobyte payload. The affected matchers are parseRgbaString, parseHslaString, parseHwbaString, parseLchaString, and parseCmykaString. This issue is fixed in version 2.9.4.

Assessing the Risk of CVE-2026-85062

Access Complexity Graph

The exploitability of CVE-2026-85062 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-2026-85062

No exploitability data is available for CVE-2026-85062.

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-2026-85062, 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-2026-85062, showing how Confidentiality, Integrity, and Availability might be affected if the vulnerability is exploited. Higher values usually signal greater potential damage.

  • Confidentiality: None
    CVE-2026-85062 does not compromise confidentiality.
  • Integrity: None
    CVE-2026-85062 does not impact data integrity.
  • Availability: None

CAPEC Common Attack Pattern Enumeration and Classification

  • Regular Expression Exponential Blowup CAPEC-492 An adversary may execute an attack on a program that uses a poor Regular Expression(Regex) implementation by choosing input that results in an extreme situation for the Regex. A typical extreme situation operates at exponential time compared to the input size. This is due to most implementations using a Nondeterministic Finite Automaton(NFA) state machine to be built by the Regex algorithm since NFA allows backtracking and thus more complex regular expressions.
