Information Disclosure
Information disclosure occurs when an application unintentionally exposes sensitive data that aids attackers in reconnaissance or directly compromises security.
How It Works
Information disclosure occurs when an application unintentionally exposes sensitive data that aids attackers in reconnaissance or directly compromises security. This happens through multiple channels: verbose error messages that display stack traces revealing internal paths and frameworks, improperly secured debug endpoints left active in production, and misconfigured servers that expose directory listings or version control artifacts like .git folders. APIs often leak excessive data in responses—returning full user objects when only a name is needed, or revealing system internals through metadata fields.
Attackers exploit these exposures systematically. They probe for common sensitive files (.env, config.php, backup archives), trigger error conditions to extract framework details, and analyze response timing or content differences to enumerate valid usernames or resources. Even subtle variations—like "invalid password" versus "user not found"—enable account enumeration. Exposed configuration files frequently contain database credentials, API keys, or internal service URLs that unlock further attack vectors.
The attack flow typically starts with passive reconnaissance: examining HTTP headers, JavaScript bundles, and public endpoints for version information and architecture clues. Active probing follows—testing predictable paths, manipulating parameters to trigger exceptions, and comparing responses across similar requests to identify information leakage patterns.
Impact
- Credential compromise: Exposed configuration files, hardcoded secrets in source code, or API keys enable direct authentication bypass
- Attack surface mapping: Stack traces, framework versions, and internal paths help attackers craft targeted exploits for known vulnerabilities
- Data breach: Direct exposure of user data, payment information, or proprietary business logic through oversharing APIs or accessible backups
- Privilege escalation pathway: Internal URLs, service discovery information, and architecture details facilitate lateral movement and SSRF attacks
- Compliance violations: GDPR, PCI-DSS, and HIPAA penalties for exposing regulated data through preventable disclosures
Real-World Examples
A major Git repository exposure affected thousands of websites when .git folders remained accessible on production servers, allowing attackers to reconstruct entire source code histories including deleted commits containing credentials. Tools like GitDumper automated mass exploitation of this misconfiguration.
Cloud storage misconfigurations have repeatedly exposed sensitive data when companies left S3 buckets or Azure Blob containers publicly readable. One incident exposed 150 million voter records because verbose API error messages revealed the storage URL structure, and no authentication was required.
Framework debug modes left enabled in production have caused numerous breaches. Django's DEBUG=True setting exposed complete stack traces with database queries and environment variables, while Laravel's debug pages revealed encryption keys through the APP_KEY variable in environment dumps.
Mitigation
- Generic error pages: Return uniform error messages to users; log detailed exceptions server-side only
- Disable debug modes: Enforce production configurations that suppress stack traces, verbose logging, and debug endpoints through deployment automation
- Access control audits: Restrict or remove development artifacts (
.git, backup files,phpinfo()) and internal endpoints before deployment - Response minimization: API responses should return only necessary fields; implement allowlists rather than blocklists for data exposure
- Security headers: Deploy
X-Content-Type-Options, remove server version banners, and disable directory indexing - Timing consistency: Ensure authentication and validation responses take uniform time regardless of input validity

In the Linux kernel, the following vulnerability has been resolved: usb: typec: tcpm: move tcpm_queue_vdm_unlocked to asynchronous work A state check was previously added to tcpm_queue_vdm_unlocked to prevent a deadlock where the DisplayPort Alt Mode driver would be executing work and attempting to grab the tcpm_lock while the TCPM was holding the lock and attempting to unregister the altmode, blocking on the altmode driver's cancel_work_sync call. Because the state check isn't protected, there is a small window where the Alt Mode driver could determine that the TCPM is in a ready state and attempt to grab the lock while the TCPM grabs the lock and changes the TCPM state to one that causes the deadlock. The callstack is provided below: [110121.667392][ C7] Call trace: [110121.667396][ C7] __switch_to+0x174/0x338 [110121.667406][ C7] __schedule+0x608/0x9f0 [110121.667414][ C7] schedule+0x7c/0xe8 [110121.667423][ C7] kernfs_drain+0xb0/0x114 [110121.667431][ C7] __kernfs_remove+0x16c/0x20c [110121.667436][ C7] kernfs_remove_by_name_ns+0x74/0xe8 [110121.667442][ C7] sysfs_remove_group+0x84/0xe8 [110121.667450][ C7] sysfs_remove_groups+0x34/0x58 [110121.667458][ C7] device_remove_groups+0x10/0x20 [110121.667464][ C7] device_release_driver_internal+0x164/0x2e4 [110121.667475][ C7] device_release_driver+0x18/0x28 [110121.667484][ C7] bus_remove_device+0xec/0x118 [110121.667491][ C7] device_del+0x1e8/0x4ac [110121.667498][ C7] device_unregister+0x18/0x38 [110121.667504][ C7] typec_unregister_altmode+0x30/0x44 [110121.667515][ C7] tcpm_reset_port+0xac/0x370 [110121.667523][ C7] tcpm_snk_detach+0x84/0xb8 [110121.667529][ C7] run_state_machine+0x4c0/0x1b68 [110121.667536][ C7] tcpm_state_machine_work+0x94/0xe4 [110121.667544][ C7] kthread_worker_fn+0x10c/0x244 [110121.667552][ C7] kthread+0x104/0x1d4 [110121.667557][ C7] ret_from_fork+0x10/0x20 [110121.667689][ C7] Workqueue: events dp_altmode_work [110121.667697][ C7] Call trace: [110121.667701][ C7] __switch_to+0x174/0x338 [110121.667710][ C7] __schedule+0x608/0x9f0 [110121.667717][ C7] schedule+0x7c/0xe8 [110121.667725][ C7] schedule_preempt_disabled+0x24/0x40 [110121.667733][ C7] __mutex_lock+0x408/0xdac [110121.667741][ C7] __mutex_lock_slowpath+0x14/0x24 [110121.667748][ C7] mutex_lock+0x40/0xec [110121.667757][ C7] tcpm_altmode_enter+0x78/0xb4 [110121.667764][ C7] typec_altmode_enter+0xdc/0x10c [110121.667769][ C7] dp_altmode_work+0x68/0x164 [110121.667775][ C7] process_one_work+0x1e4/0x43c [110121.667783][ C7] worker_thread+0x25c/0x430 [110121.667789][ C7] kthread+0x104/0x1d4 [110121.667794][ C7] ret_from_fork+0x10/0x20 Change tcpm_queue_vdm_unlocked to queue for tcpm_queue_vdm_work, which can perform the state check while holding the TCPM lock while the Alt Mode lock is no longer held.

A heap-buffer-overread vulnerability was found in GnuTLS in how it handles the Certificate Transparency (CT) Signed Certificate Timestamp (SCT) extension during X.509 certificate parsing. This flaw allows a malicious user to create a certificate containing a malformed SCT extension (OID 1.3.6.1.4.1.11129.2.4.2) that contains sensitive data. This issue leads to the exposure of confidential information when GnuTLS verifies certificates from certain websites when the certificate (SCT) is not checked correctly.

In the Linux kernel, the following vulnerability has been resolved: ASoC: codecs: wcd9335: Fix missing free of regulator supplies Driver gets and enables all regulator supplies in probe path (wcd9335_parse_dt() and wcd9335_power_on_reset()), but does not cleanup in final error paths and in unbind (missing remove() callback). This leads to leaked memory and unbalanced regulator enable count during probe errors or unbind. Fix this by converting entire code into devm_regulator_bulk_get_enable() which also greatly simplifies the code.
In the Linux kernel, the following vulnerability has been resolved: mm/damon/sysfs-schemes: free old damon_sysfs_scheme_filter->memcg_path on write memcg_path_store() assigns a newly allocated memory buffer to filter->memcg_path, without deallocating the previously allocated and assigned memory buffer. As a result, users can leak kernel memory by continuously writing a data to memcg_path DAMOS sysfs file. Fix the leak by deallocating the previously set memory buffer.

In the Linux kernel, the following vulnerability has been resolved: ALSA: usb-audio: Fix out-of-bounds read in snd_usb_get_audioformat_uac3() In snd_usb_get_audioformat_uac3(), the length value returned from snd_usb_ctl_msg() is used directly for memory allocation without validation. This length is controlled by the USB device. The allocated buffer is cast to a uac3_cluster_header_descriptor and its fields are accessed without verifying that the buffer is large enough. If the device returns a smaller than expected length, this leads to an out-of-bounds read. Add a length check to ensure the buffer is large enough for uac3_cluster_header_descriptor.

In the Linux kernel, the following vulnerability has been resolved: mm: userfaultfd: fix race of userfaultfd_move and swap cache This commit fixes two kinds of races, they may have different results: Barry reported a BUG_ON in commit c50f8e6053b0, we may see the same BUG_ON if the filemap lookup returned NULL and folio is added to swap cache after that. If another kind of race is triggered (folio changed after lookup) we may see RSS counter is corrupted: [ 406.893936] BUG: Bad rss-counter state mm:ffff0000c5a9ddc0 type:MM_ANONPAGES val:-1 [ 406.894071] BUG: Bad rss-counter state mm:ffff0000c5a9ddc0 type:MM_SHMEMPAGES val:1 Because the folio is being accounted to the wrong VMA. I'm not sure if there will be any data corruption though, seems no. The issues above are critical already. On seeing a swap entry PTE, userfaultfd_move does a lockless swap cache lookup, and tries to move the found folio to the faulting vma. Currently, it relies on checking the PTE value to ensure that the moved folio still belongs to the src swap entry and that no new folio has been added to the swap cache, which turns out to be unreliable. While working and reviewing the swap table series with Barry, following existing races are observed and reproduced [1]: In the example below, move_pages_pte is moving src_pte to dst_pte, where src_pte is a swap entry PTE holding swap entry S1, and S1 is not in the swap cache: CPU1 CPU2 userfaultfd_move move_pages_pte() entry = pte_to_swp_entry(orig_src_pte); // Here it got entry = S1 ... < interrupted> ... <swapin src_pte, alloc and use folio A> // folio A is a new allocated folio // and get installed into src_pte <frees swap entry S1> // src_pte now points to folio A, S1 // has swap count == 0, it can be freed // by folio_swap_swap or swap // allocator's reclaim. <try to swap out another folio B> // folio B is a folio in another VMA. <put folio B to swap cache using S1 > // S1 is freed, folio B can use it // for swap out with no problem. ... folio = filemap_get_folio(S1) // Got folio B here !!! ... < interrupted again> ... <swapin folio B and free S1> // Now S1 is free to be used again. <swapout src_pte & folio A using S1> // Now src_pte is a swap entry PTE // holding S1 again. folio_trylock(folio) move_swap_pte double_pt_lock is_pte_pages_stable // Check passed because src_pte == S1 folio_move_anon_rmap(...) // Moved invalid folio B here !!! The race window is very short and requires multiple collisions of multiple rare events, so it's very unlikely to happen, but with a deliberately constructed reproducer and increased time window, it can be reproduced easily. This can be fixed by checking if the folio returned by filemap is the valid swap cache folio after acquiring the folio lock. Another similar race is possible: filemap_get_folio may return NULL, but folio (A) could be swapped in and then swapped out again using the same swap entry after the lookup. In such a case, folio (A) may remain in the swap cache, so it must be moved too: CPU1 CPU2 userfaultfd_move move_pages_pte() entry = pte_to_swp_entry(orig_src_pte); // Here it got entry = S1, and S1 is not in swap cache folio = filemap_get ---truncated---

Fix it by applying a similar fix for anon mTHP swapin. The performance change is very slight, time of swapin 10g zero folios with shmem (test for 12 times): Before: 2.47s After: 2.48s [[email protected]: add comment]

The SureForms - Drag and Drop Form Builder for WordPress plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 1.7.3 via the use of file_exists() in the delete_entry_files() function without restriction on the path provided. This makes it possible for unauthenticated attackers to inject a PHP Object. No known POP chain is present in the vulnerable software, which means this vulnerability has no impact unless another plugin or theme containing a POP chain is installed on the site. If a POP chain is present via an additional plugin or theme installed on the target system, it may allow the attacker to perform actions like delete arbitrary files, retrieve sensitive data, or execute code depending on the POP chain present.
