The CVE record names the fixed release — apply it.

Weblate is a web-based continuous localization platform used to manage software translations. In versions prior to 2026.7, a user with the built-in "Edit source" role can store a malicious regular expression in a source string's flags that is executed without any timeout, allowing them to stall requests and deny service. Regular expressions supplied through the regex: quality check and regex placeholders are compiled during validation but later run against translation content in RegexCheck and PlaceholderCheck with no time limit, so a catastrophic-backtracking pattern like ^(a|aa)+$ can consume CPU indefinitely. Because Weblate re-runs these checks for every linked target unit in the same request when a source unit's flags change, a single edit can trigger sustained CPU-bound denial of service. This issue is fixed in version 2026.7.

The CVE record names the fixed release. Apply it within your standard update timelines.

Exploitation none (CISA Vulnrichment) · Automatable no (CISA Vulnrichment) · Technical impact partial (CISA Vulnrichment). All three are CISA's SSVC values (Vulnrichment). EchelonGraph applied CISA's decision table to them; CISA publishes SSVC inputs and the table, not a decision for each CVE. Mission impact is CISA's Mission & Well-being decision point, and only you can judge it. CISA's table makes it high when Mission Prevalence is Essential — the vulnerable component "directly provides capabilities that constitute at least one MEF for at least one entity" (MEF: mission essential function) — or when Public Well-Being Impact is Irreversible: "multiple fatalities are likely", the cyber-physical system "is likely lost or destroyed", "extreme or serious externalities" are imposed on other parties, or social systems such as elections or the financial grid "are destabilized and potentially collapse".
