The CVE record names the fixed release — apply it.

(conda) Constructor is a tool which allows constructing an installer for a collection of conda packages. Prior to version 3.11.3, shell installer scripts process the installation prefix (user_prefix) using an eval statement, which executes unsanitized user input as shell code. Although the script runs with user privileges (not root), an attacker could exploit this by injecting arbitrary commands through a malicious path during installation. Exploitation requires explicit user action. This issue has been patched in version 3.11.3.

Data Freshness Timeline

(refreshed 7× in last 7d / 38× in last 30d)

Each row is a time one of our pipelines fetched, updated or re-scored this CVE. For example, "NVD update" means NVD published or revised its analysis for this CVE; "MITRE cvelistV5" means we ingested or refreshed it from the CNA feed. An arrow marks a change the record states ("CVSS v3 → 9.1"); EPSS and GHSA rows show the values recorded at that time, not what changed (EPSS values are rounded; hover one for the exact figures). Most recent first.

Showing the most recent 95 of 230 refreshes on record for this CVE.

A repeat, a row identical to one the same pipeline wrote less than 10 seconds earlier, is not a separate refresh and is not counted. 5 repeat rows among the latest 100 are merged into the row they repeat. The 135 oldest rows on record are not shown and were not checked, so the counts can still include repeats.
