EspoCRM is an open source customer relationship management application. In versions 9.3.3 and below, the POST /api/v1/Email/importEml endpoint contains an Insecure Direct Object Reference (IDOR) vulnerability where the attacker-supplied fileId parameter is used to fetch any attachment directly from the repository without verifying that the current user has authorization to access it. Any authenticated user with Email:create and Import permissions can exploit this to read another user's .eml attachment contents by importing them as a new email into the attacker's mailbox, while the original victim attachment record is deleted as a side effect of the import flow. This is inconsistent with the standard attachment download path, which enforces ACL checks before returning file data, and is practically exploitable because attachment IDs are commonly exposed in normal UI and API workflows such as stream payloads and download links. This issue is fixed in version 9.3.4.

### Summary A broken access control vulnerability allows unauthenticated users to retrieve note assets directly from the asset download endpoint when they know both the note UUID and asset UUID. This exposes the full contents of private note assets without authentication, even when the associated book is not public. ### Details The issue is caused by the asset download route being registered without authentication middleware. Relevant route registration: - `handlers/assets.go`, line 40 ```go huma.Get(api, "/api/notes/{noteID}/assets/{assetID}", h.GetNoteAssetContentByID) ``` By contrast, other asset operations correctly apply authentication middleware. For example: ```go huma.Delete(api, "/api/notes/{noteID}/assets/{assetID}", h.DeleteNoteAsset, huma.WithMiddleware(h.authMiddleware.AuthRequiredMiddleware)) ``` The backend service for asset retrieval also does not enforce ownership or visibility checks. According to the provided code references, the lookup only queries the asset table by asset ID and note ID: ```sql SELECT * FROM note_assets WHERE id = ? AND note_id = ? ``` Because the retrieval path does not join against the related `notes` or `books` records, it does not verify: - whether the requester owns the parent book - whether the parent book is public or private - whether the related note has been deleted As a result, possession of a valid `noteID` and `assetID` is sufficient to retrieve the asset binary, regardless of whether the note belongs to a private book. The exploitability is constrained by identifier knowledge. Both `noteID` and `assetID` are UUIDv4 values, so blind guessing is impractical. However, the endpoint remains vulnerable whenever those identifiers are disclosed through another channel, such as leaked links, browser history, proxy logs, shared URLs, or other application behaviors that expose internal asset references. ### PoC The issue can be reproduced by creating a private note with an attached asset, then requesting the asset download endpoint without authentication using the valid `noteID` and `assetID`. The server returns the asset content even though the associated note is private. ### Impact - **Type:** Broken access control / unauthenticated information disclosure - **Who is impacted:** Any deployment exposing the affected asset download endpoint - **Security impact:** Full binary contents of private note assets can be disclosed to unauthenticated users who know the required identifiers - **Attack preconditions:** The attacker must know both the target `noteID` and `assetID`; no authentication is required - **Attack complexity:** High, because successful exploitation depends on prior disclosure of both UUIDs rather than feasible online guessing

Net::CIDR::Lite before version 0.23 for Perl incorrectly handles RFC 4291 IPv4-mapped IPv6 addresses (::ffff:x.x.x.x) by including an extra sentinel byte during packing, resulting in 18-byte instead of 17-byte representations. This misalignment causes the find() and bin_find() functions to return incorrect matching results during IP address lookup operations, enabling attackers to bypass IP-based access control lists by crafting addresses that fall outside intended CIDR ranges. No active exploitation has been identified, but the low EPSS score (0.02%) masks the authentication bypass tag, suggesting limited real-world triggering conditions despite the 6.5 CVSS score.

IPv6 address validation bypass in Net::CIDR::Lite for Perl (versions <0.23) allows remote attackers to circumvent IP access control lists without authentication. The _pack_ipv6() function fails to validate that uncompressed IPv6 addresses contain exactly 8 hexadecimal groups, accepting malformed inputs like 'abcd' or '1:2:3' and producing incorrect packed representations. This causes find() and bin_find() methods to incorrectly match addresses against CIDR ranges, enabling ACL bypass. Exploitati

Microsoft Edge (Chromium-based) on Android contains a user interface misrepresentation vulnerability that allows unauthenticated remote attackers to conduct spoofing attacks over a network. The vulnerability exploits UI rendering to misrepresent critical information to end users, enabling attackers to deceive users into taking unintended actions.
