VC:N - no confidentiality impact; the attacker does not read data they cannot already access. VI:H - high integrity impact: an existing model belonging to another organisation can be overwritten in place, its ownership reassigned, or its default flag set, altering scoring for other users. VA:N - no availability impact. SC/SI/SA:N - the impact is confined to the MISP instance itself (same component); no secondary component is affected.

The save operation is preceded by an explicit create() call and the data is wrapped in the proper model key, preventing the ORM from interpreting attacker-supplied nested keys as separate model attributes.",

A DecayingModel::create() call was added before save, and the save payload is now wrapped as array(\u0027DecayingModel\u0027 =\u003e $model) to bind the data to the correct model context. A regression test (DecayingModelImportOwnership) was added that verifies a nested DecayingModel key with a foreign id, org_id, and default=1 cannot overwrite or reassign an existing model.",

The incomplete server-side authorization check then permits the operation. CAPEC-10 is the closest available pattern for exploiting a server\u0027s failure to properly validate the authorization context of a user-supplied resource identifier. Uncertainty: no CAPEC specifically named \u0027Insecure Direct Object Reference\u0027 or \u0027Broken Access Control via Incomplete ACL\u0027 exists in the CAPEC catalog, so Parameter Tampering is the best available match."

In fetchEvent(), when flatten is true and the user is not a site admin, a similar subquery is injected into the Attribute contain conditions. The second commit refactors the ACL condition into a standalone variable ($objectAclCondition) and uses only that condition (plus Object.id = Attribute.object_id) in the subquery, removing the soft-delete and other contain conditions that were incorrectly included. A regression test class (FlattenedObjectAcl) in tests/testregressions.py verifies: (1) an outsider cannot see organisation-only object attributes via flatten, (2) the owner retains soft-deleted attributes of a live object, and (3) the outsider cannot see another org\u0027s soft",

The login proceeds only if both the TOTP verification and the claim succeed. Thirteen lines added, one line modified.",

Additionally, the cached OTP user session entry is deleted immediately after a successful login (for both TOTP and HOTP paths), preventing the stale session state from being reused.",

CorrelationGraphTool::__createNode() now checks the icon against the validator and substitutes \u0027globe\u0027 for invalid stored values. Both correlation-graph.js and correlation-graphOvermind.js were changed from .html() string concatenation to .attr(\u0027class\u0027, ...) with a regex strip of non-conforming characters. AppController asset query version bumped from 225 to 226.

A DecayingModel::create() call was added before save, and the save payload is now wrapped as array(\u0027DecayingModel\u0027 =\u003e $model) to bind the data to the correct model context. A regression test (DecayingModelImportOwnership) was added that verifies a nested DecayingModel key with a foreign id, org_id, and default=1 cannot overwrite or reassign an existing model.",

UI:A - the victim must actively view the event preview and interact with the tag element. VC/VI/VA:N - the MISP server itself is not compromised; the impact is in the victim\u0027s browser. SC:N - no meaningful confidentiality impact on the subsequent component is guaranteed.
