conda-smithy is a tool for combining a conda recipe with configurations to build using freely hosted CI services into a single repository. Prior to version 3.47.1, the travis_encrypt_binstar_token implementation in the conda-smithy package has been identified as vulnerable to an Oracle Padding Attack. This vulnerability results from the use of an outdated and insecure padding scheme during RSA encryption. A malicious actor with access to an oracle system can exploit this flaw by iteratively submitting modified ciphertexts and analyzing responses to infer the plaintext without possessing the private key. This issue has been patched in version 3.47.1.
CVE-2025-49824
This low-severity CVE scores 1.7 under NVD CVSS v3. EPSS exploit probability: 0.2%, top 84% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).
- Lower severity and no public exploit yet
No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.
