Published 4.13.0.92 wheels bundle ffmpeg 5.1.x despite build Dockerfiles specifying 8.0.1

[lawrence-u10d]

Summary

The published PyPI wheels for opencv-python 4.13.0.92 (and opencv-python-headless, opencv-contrib-python) bundle ffmpeg 5.1.x (libavcodec.so.59.37.100), despite the build Dockerfiles in this repository specifying FFMPEG_VERSION=8.0.1 as of commit d098302 (Jan 6, 2026).

This results in 14 unresolved CVEs flagged by vulnerability scanners (grype, etc.) in any Docker image that installs these wheels.

Reproduction

pip download --no-deps \
  --platform manylinux_2_28_aarch64 \
  --python-version 312 --abi cp312 \
  opencv-python-headless==4.13.0.92

unzip -l opencv_python_headless-4.13.0.92-cp37-abi3-manylinux_2_28_aarch64.whl \
  | grep libav

Output:

 11871529  02-05-2026 08:39   opencv_python_headless.libs/libavcodec-5696b3bf.so.59.37.100

   656777  02-05-2026 08:39   opencv_python_headless.libs/libswscale-27999517.so.6.7.100

libavcodec.so.59 = ffmpeg 5.1.x. ffmpeg 8.0.1 would be libavcodec.so.61.

Expected

The wheels should bundle ffmpeg 8.0.1 as specified in the build Dockerfiles (docker/manylinux_2_28/Dockerfile_aarch64, docker/manylinux2014/Dockerfile_aarch64, etc.) which were updated in d098302.

Impact

The following CVEs are present in the bundled ffmpeg 5.1.6 and would be resolved by ffmpeg 8.0.1:

High:

• CVE-2025-1594
• CVE-2025-9951
• CVE-2023-49502
• CVE-2023-6605
• CVE-2023-50010
• CVE-2023-50008
• CVE-2024-31582

Medium:

• CVE-2023-6602, CVE-2025-0518, CVE-2025-25469, CVE-2025-25468, CVE-2023-6604, CVE-2025-22919, CVE-2025-59729, CVE-2023-6601, CVE-2025-59730, CVE-2023-50007

Likely Cause

The CI build images used to compile the wheels appear to have been cached/stale and were not rebuilt from the updated Dockerfiles before publishing release 92.
