CWE-359
Exposure of Private Personal Information to an Unauthorized Actor
Monthly
Information disclosure in Firefox's Form Autofill component exposes sensitive personal data stored by the browser to unauthorized actors via a network-accessible, unauthenticated attack path scored CVSS 7.5 (AV:N/AC:L/PR:N/UI:N/C:H). All Firefox versions prior to 154 and Firefox ESR versions prior to 153.1 are affected, with Mozilla issuing four separate security advisories (mfsa2026-74, mfsa2026-77, mfsa2026-78, mfsa2026-80) across release channels. No public exploit or CISA KEV listing has been identified at time of analysis, and the EPSS exploitation probability stands at 0.14% (4th percentile).
Use-after-free memory corruption in Firefox's Layout: Text and Fonts component allows a remote unauthenticated attacker to achieve high-confidence confidentiality, integrity, and availability impact by luring a user to visit a malicious web page. The vulnerability spans the main Firefox release channel and all three active ESR branches (115.x, 140.x, 153.x), indicating broad exposure across enterprise and consumer deployments. No public exploit or active exploitation has been identified at time of analysis, but the network-accessible, low-complexity nature of this flaw and the breadth of MFSA advisories (mfsa2026-74 through mfsa2026-80) signal a high-priority patching target.
Information disclosure in Qualcomm Snapdragon chipsets exposes private data transmitted during NG-eCall SIP signaling when IPSec negotiation fails or is improperly established. Attackers adjacent to the network can intercept unprotected signaling traffic, gaining access to sensitive session data - potentially including location coordinates and caller identity transmitted as part of the automated emergency call system. No public exploit code has been identified at time of analysis, and the vulnerability is not listed in the CISA KEV catalog.
Information disclosure in Microsoft Remote Desktop Web Client (before 2.1.65.2) and Windows Admin Center (before 2.7.4) allows unauthenticated remote attackers to read private personal information over the network without user interaction. The CVSS 7.5 rating reflects high confidentiality impact with no integrity or availability effect. There is no public exploit identified at time of analysis, and the low EPSS score (0.55%, 42nd percentile) suggests limited near-term exploitation likelihood despite the network-reachable, unauthenticated vector.
Microsoft Defender for Endpoint for Mac exposes private personal information to locally authenticated attackers through an information disclosure flaw tracked as CWE-359. Affected versions span the entire release line below 101.26042.0020, where a low-privileged local attacker operating under high-complexity conditions can read sensitive data that should remain confidential to the security product itself. No public exploit or active exploitation has been identified; SSVC rates the technical impact as partial and exploitation likelihood as none, consistent with the low EPSS score of 0.41% at the 33rd percentile.
Information disclosure in Microsoft Edge for Android (Chromium-based) allows a network-based attacker to expose a victim's private personal information, but only after luring the user into interacting with attacker-controlled content (UI:R). The flaw carries a CVSS 7.1 rating driven by high confidentiality impact; there is no public exploit identified at time of analysis and it is not listed in CISA KEV. A vendor patch is available via Microsoft's MSRC update guide.
Information disclosure in Microsoft Edge for Android allows a remote unauthenticated attacker to exfiltrate private personal information over the network when a victim interacts with attacker-controlled content. The flaw carries a CVSS 7.1 with high confidentiality impact and stems from private data being exposed to an unauthorized actor (CWE-359); Microsoft has released a fix. No public exploit identified at time of analysis and it is not listed in CISA KEV.
Unauthenticated attendee PII exposure in Hi.Events through 1.9.0 lets remote attackers retrieve full attendee lists — including names, emails, and personal information — by hitting the public check-in list endpoints, which treat the check-in list's short_id as the only access control. Beyond reading data, an attacker who knows or guesses a short_id can also create and delete check-in records without authentication. No public exploit identified at time of analysis; the issue was reported by VulnCheck and is tracked via an upstream GitHub fix.
Unauthenticated information disclosure in phpUploader before 2.0.2 lets remote attackers harvest the entire uploaded-files database table simply by loading any page of the application. The index model runs an unbounded SELECT and serializes the full result set into an inline JSON script block, leaking uploader IP addresses, Argon2ID key hashes, internal filenames, and SHA-256 fingerprints. No public exploit identified at time of analysis, but the data is exposed in plain HTML source on every page, making extraction trivial; CVSS 4.0 base is 8.7 (High).
Authorization bypass in Mercator information system mapping application prior to version 2025.05.19 allows any authenticated user - including the read-only Auditor role - to query arbitrary Eloquent models via the unprotected `/admin/queries/execute` endpoint. The flaw permits enumeration of the `User` model and even allows the supposedly `$hidden` `password` column to be probed via `LIKE` filter predicates, enabling blind extraction of password hashes. No public exploit identified at time of analysis, but the vendor advisory (GHSA-q3r8-3h7c-96w3) confirms the issue and ships a fix.
