Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Two packages are affected: trytond and proteus. Trytond versions 5.0.0 before 5.0.46, 6.0.0 before 6.0.16, and 6.1.0 before 6.2.6 are vulnerable, and proteus versions 5.0.0 before 5.0.12, 6.0.0 before 6.0.5, and 6.1.0 before 6.2.2 are vulnerable. An authenticated user can submit a crafted XML SEPA file that makes the server read arbitrary files from the system. Upgrade trytond to 5.0.46, 6.0.16, or 6.2.6, and proteus to 5.0.12, 6.0.5, or 6.2.2, matching your release line.
