Name of the Vulnerable Software and Affected Versions LiquidJS versions 10.26.0 through 10.27.0
Description The strip html filter in src/filters/html.ts can enter an infinite loop when processing an input string that contains a < character, has at least one preceding character, and lacks a subsequent > character. This occurs because the search for the next opener advances the lt variable while the loop index remains unchanged when the closer search returns -1, preventing the stall guard from exiting. This behavior blocks template rendering and can lead to a denial of service.
Recommendations Update to version 10.27.1.
