Real-World Exposure
tqdmReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects PyPI packages — download data is not available via public APIs for these ecosystems.
Description
tqdm is an open source progress bar for Python and CLI. Any optional non-boolean CLI arguments (e.g. --delim, --buf-size, --manpath) are passed through python's eval, allowing arbitrary code execution. This issue is only locally exploitable and had been addressed in release version 4.66.3. All users are advised to upgrade. There are no known workarounds for this vulnerability.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for tqdm, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update tqdm to 4.66.3 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2024-34062 is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
Fixing This On Your OS
If you run this on a Linux distribution, patch through your package manager against the distro's own security advisory below — it tracks the exact backported fix for your release, which can ship on a different timeline (and sometimes a different severity) than the upstream project.
This flaw can only be triggered when python-tqdm is used directly via the command line with crafted arguments for non-boolean parameters such as `delim`, `buf-size`, and `manpath`. The rust-srpm-macros package as shipped by Red Hat Enterprise Linux 8 and 9 is not vulnerable to this issue because it does not use the…
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.Source: Red Hat security advisory for CVE-2024-34062 (CC BY 4.0)
