| 标题 | uBlock @gorhill/ubo-core >=npm_0.1.11 Inefficient Regular Expression Complexity |
|---|
| 描述 | A potential Regular Expression Denial of Service (ReDoS)vulnerability in the 1p-filters.js script of uBlock Origin. The vulnerabilityoccurs due to the use of the regular expression /\s+$/, which is used to removetrailing whitespace. This issue can lead to a denial of service when processingstrings with a large number of trailing spaces, potentially causing a browser tofreeze.
The regular expression /\s+$/ is applied to remove trailing whitespace in user‑provided content. However, when the content has a large number of spaces(e.g., ~100,000), this pattern causes excessive backtracking in the regularexpression engine, resulting in performance degradation and UI freezing. This is a classic ReDoS attack vector. |
