CVE-2023-27578 | Galaxy vulnerable to unauthorized modification of pages/visualizations due to insufficient permission check

Galaxy is an open-source platform for data analysis. All supported versions of Galaxy are affected prior to 22.01, 22.05, and 23.0 are affected by an insufficient permission check. Unsupported versions are likely affected as far back as the functionality of Visualizations/Pages exists. Due to this issue, an attacker can modify or delete any Galaxy Visualization or Galaxy Page given they know the encoded ID of it. Additionally, they can copy or import any Galaxy Visualization given they know the encoded ID of it. Patches are available for versions 22.01, 22.05, and 23.0. For the changes to take effect, you must restart all Galaxy server processes. There are no supported workarounds.

9.1 3.1 CRITICAL
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:H Click to expand
Attack vector (AV:N)
Could be attacked over the internet or any normal routed network—not just someone sitting at the machine.
Attack complexity (AC:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
Privileges required (PR:N)
No account or special rights needed—anonymous or random user is enough.
User interaction (UI:N)
Nobody has to click “OK” or open a trap file; it can work without a victim helping.
Scope (S:U)
Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:N)
Doesn’t really leak secrets in a meaningful way.
Integrity (I:H)
They could widely tamper with or forge data—trust in the data is badly hurt.
Availability (A:H)
Could take the service down hard or make it unusable for people who depend on it.
