Security readout for executives and security teams
Plain-English summary
A low-privileged user of usememos memos v0.25.2 may be able to change or delete attachments created by other users. The business concern is cross-user data tampering in a collaborative note system, not remote takeover. The source bundle does not name a fixed version.
Executive priority
Treat this as a moderate-priority integrity issue. It matters most for organizations relying on memos for shared notes, internal documentation, or user-uploaded attachments. Prioritize confirmation and patch tracking, especially on internet-accessible or broadly shared instances.
Technical view
CVE-2025-65798 is an incorrect access control issue, CWE-284, in usememos memos v0.25.2. CVSS 3.1 is 5.4: network reachable, low complexity, low privileges required, no user interaction, unchanged scope, low confidentiality and integrity impact, no availability impact.
Likely exposure
Exposure is most likely where usememos memos v0.25.2 is deployed with multiple authenticated users and attachments. The structured affected-product fields are listed as n/a, so teams should confirm exact affected and fixed versions from upstream project guidance.
Exploitation context
The CVE is not listed as CISA KEV in the provided bundle, and no cited source states active exploitation. The described attacker already has low-level application privileges and can target other users' attachments through an access-control failure.
Researcher notes
Evidence is limited to the CVE metadata, upstream PR, and advisory links. The bundle does not provide exploit details, a fixed release, or complete structured affected-product data. Avoid assuming broader version impact without vendor confirmation.
Mitigation direction
- Inventory usememos memos deployments and identify any running v0.25.2.
- Review the upstream PR and advisory for official fixed-version guidance.
- Restrict memos access to trusted users until remediation is confirmed.
- Back up user attachments before applying upgrades or configuration changes.
- Monitor attachment modification and deletion events for cross-user anomalies.
Validation and detection
- Confirm deployed memos versions against v0.25.2 and vendor guidance.
- Review application roles and attachment ownership enforcement.
- Audit logs for attachment changes made by non-owners.
- In authorized testing, verify users cannot alter another user's attachments.
- Document whether a patched release or workaround has been applied.

Improper Access Control
Improper Access Control represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
