Real-World Exposure
enrocryptReal-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
Impact
The vulnerability is we used MD5 hashing Algorithm In our hashing file. If anyone who is a beginner(and doesn't know about hashes) can face problems as MD5 is considered a Insecure Hashing Algorithm.
Patches
The vulnerability is patched in v1.1.4 of the product, the users can upgrade to version 1.1.4.
Workarounds
If u specifically want a version and don't want to upgrade, you can remove the MD5 hashing function from the file hashing.py and this vulnerability will be gone

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for enrocrypt, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update enrocrypt to 1.1.4 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2021-39182 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.
