EcoStruxure Power Build Rapsody: Use-after-free via malicious project file
Summary
Schneider Electric EcoStruxure Power Build Rapsody, a switchboard design and bill-of-materials tool, contains a use-after-free vulnerability (CWE-416). A local attacker who tricks a user into opening a specially crafted file could execute arbitrary code on the engineering workstation. The attack requires user interaction and no privileges, and the product is not network-facing.
Affected
- EcoStruxure Power Build Rapsody FR-V2.9.1.0 and prior
- ESP-V2.8.5.0301 and prior
- PT-V2.8.7.0101 and prior
- BEL(FR)-V2.8.8.0201 and prior
- BEL(EN)-V2.8.3.0201 and prior
- INT(EN)-V2.8.4.0401 and prior
- INT(FR)-V2.8.6.0000 and prior
- NL-V2.8.2.0000 and prior
The advisory states that only versions still supported or under warranty are listed as affected.
Fixed in
- FR V2.9.12.0101 (per secondary source, verify in advisory)
- ESP V2.9.5.0000 (per secondary source, verify in advisory)
- PT V2.9.7.0000 (per secondary source, verify in advisory)
- BEL(FR) V2.9.8.0000 (per secondary source, verify in advisory)
- BEL(EN) V2.9.3.0000 (per secondary source, verify in advisory)
- INT(EN): Unknown.
- INT(FR): Unknown.
- NL: Unknown.
The advisory states that a fix is available for download from Schneider Electric.
Workaround
Unknown. Schneider Electric's interim mitigations for unpatched versions could not be confirmed.
- Do not open project files from unknown or untrusted sources on engineering workstations.
- Restrict who can open project files and encrypt stored project files (general good practice, based on earlier Rapsody advisories).
Exploitation
- No exploitation reported in the advisory.
- No CISA KEV listing and no public exploit code known as of 11 Nov 2026 (OffSeq, VulDB).
Our recommendation
- Inventory all Rapsody installations and record the regional edition and full version.
- Update to the fixed builds from the advisory, prioritising FR, ESP, PT, BEL and INT. Confirm the fixes for INT(EN), INT(FR) and NL directly with Schneider Electric.
- Until patched, restrict who can open project files and avoid unvetted files.
- Re-check the advisory SEVD-2026-314-01 and the NVD entry for changes.
Public exploits
PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.
