CVE-2026-69659 is a medium-severity flaw (CVSS 5.5) affecting ash framework. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

Uncontrolled Resource Consumption vulnerability in ash-project ash allows an attacker to exhaust the memory of the node via a crafted keyset pagination cursor. Read actions with keyset pagination deserialize the client-supplied page[:after] or page[:before] cursor in decode_values/2 in lib/ash/page/keyset.ex, which base64-decodes the value and passes it to :erlang.binary_to_term/2 without bounding its size. The Erlang external term format suppor

ash-hq ash framework UPGRADE

Affected: >= 1.17.0 and < 3.31.1

Fixed in: 3.31.1

Safe to downgrade to: a release before 1.17.0

1. Check installed version

apt-cache policy ash-framework || rpm -q ash-framework || ash-framework --version

2. UPGRADE to 3.31.1 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade ash-framework

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade ash-framework

Note

Distros often backport fixes without changing the version number. Confirm with the distro advisory or changelog.

3. If no update is available yet, DOWNGRADE to a release before 1.17.0 (Debian / Ubuntu)

apt-cache madison ash-framework sudo apt install ash-framework=<VERSION_BEFORE_1.17.0> sudo apt-mark hold ash-framework

3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list ash-framework sudo dnf downgrade ash-framework-<VERSION_BEFORE_1.17.0> sudo dnf versionlock add ash-framework

Downgrade risk

Downgrading can break dependent software and may reopen older bugs. Read the distro advisory first and test on a non-production host.

After downgrade

Restart the service, and keep the package held until a fixed release ships.
