What is CVE-2025-49824?
CVE-2025-49824 is a low-severity vulnerability in conda-forge conda-smithy, published on 17 Jun 2025. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
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 This vulnerability results from the use of an outdated and insecure padding scheme during RSA encryption.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.
Weakness: CWE-200
