Fixes released after 10.3 Update-3 (10.3.3 rev. 012336):
| Ref. | Description |
|---|---|
| PDXP-11111, PDXP-9109 | Security enhancement |
| 623800 | High memory usage during index rebuild caused by SolrFullBatchUpdateContext |
| PDXP-13381/484103 | SwitchOnRebuildSolrCloudSearchIndex should use Solr aliases to determine active and rebuild collections instead of local properties. This revises previous fix PDXP-697/484103 (below); please see the appliable instructions file. |
Fixes released between 10.3 Update-2 (10.3.2 rev. 010837) and 10.3 Update-3 (10.3.3 rev. 012336):
| Ref. | Description |
|---|---|
| PDXP-7886, PDXP-7591/PDXP-1052/624115, PDXP-7180, PDXP-5517/629358, 628372, 619349 | Security enhancements |
| PDXP-11391 | The installation of security patch Sitecore.Support.10.0-10.4.zip from Sitecore Security Bulletin SC2025-003 can fail to initialize with an uncaught exception. MembershipPasswordException: The user account has been locked out. |
| PDXP-6822, 601123 | The /fieldtracking/register endpoint is incorrectly logged as a page view event in Experience Analytics when users interact with form fields. This inflates analytics data with non-navigational events, leading to inaccurate reporting and cluttered page view metrics. |
| PDXP-6246/626523 | Search Operations ignore the quotation marks |
| PDXP-5587 | Introduced a lightweight, secure tracking script to help us better understand how Sitecore’s management UIs are used. This will help us ensure future enhancements are guided by real-world usage patterns. No content, website data, or website visitor information is tracked. Tracking respects privacy settings and licensing controls. |
| PDXP-697/484103 | SwitchOnRebuildSolrCloudSearchIndex should use Solr aliases to determine active and rebuild collections instead of local properties |
| 628079 | When a user edits an existing segment in a segmented list and modifies its rules, the "Save" button becomes inactive, preventing the user from saving the changes |
| 626450 | Incorrect Content-Type header returned by Media Library search request |
| 626064 | The <br> tag causes validation errors in the Rich Text Editor field |
| 625158 | ExperienceOptimization.ContentTesting throws a NullReferenceException when reference.RenderingItem is null |
| 624954 | An new log folder gets created when a new language is added in the Content Editor, instead of using the existing log folder. This issue occurs in Azure Web App deloyments of Sitecore XP |
| 624167 | Pages may disappear after publishing |
| 624166 | In Live Mode, Sitecore fails to resolve item paths correctly, leading to incorrect or broken URLs when rendering content |
| 623948 | The Sitecore OData API ( /sitecore/api/ssc/aggregate/content ) returns child items even when those items do not have a version in the requested language ( sc_lang ), resulting in inaccurate API responses |
| 622654 | When retrieving an item in Edit mode, Sitecore incorrectly stores the resolved version (typically the latest publishable version) in the main item cache instead of the FilteredItemsCache . This causes subsequent requests in Normal mode to return the wrong version (e.g., version 1 instead of version 2) |
| 621268 | Added the ability to enable Connection Strings in Microsoft's Azure Monitor - Application Insights feature, in response to Microsoft declaring end of support for Instrumentation Key Ingestion as of March 31, 2025; ref: KB1003554. To assist in implementing this change, a new set of ARM Templates are provided. See ARM Templates Sitecore 10.3.3. |
| 620439 | Due to a race condition in the Solr indexing process, the _content field may inconsistently omit text field values when indexing items in parallel. This leads to incomplete or inconsistent full-text search results, especially in large-scale content structures with many fields and high concurrency settings |
| 620009 | Checkbox and checklist fields unintentionally unchecked or marked as modified due to race condition in Content Editor Search navigation |
| 619146 | When using the RemovePrefix(string) method on a Sitecore.Caching.Generics.Cache<TKey> instance under high concurrency, significant lock contention can occur due to the use of GetCacheKeys() , which locks the cache |
| 618843 | Under high load, Sitecore's device detection engine can exhaust available threads due to low concurrency settings and disk-based lookups. This leads to unhandled exceptions and crashes the instance |
| 618639 | The MediaRequestHandler ignores the value of MediaResponse.Cacheability setting |
| 617089 | If the CM instance is restarted during email dispatch, the campaign remains stuck in the "Sending" state. Attempts to pause it show a confirmation, but the status doesn't update to "Paused", and the "Resume" button is missing, preventing recovery |
| 612595 | When a Droplist field uses a query-based source (e.g., with query axes or @@ syntax), selecting and saving a value results in a false broken link warning in the Content Editor |
| 605862 | English version is created after Remove Broken Links admin tool is used. Running the tool causes a new English version to be created unintentionally |
| 598738 | Added optional automation to simplify installing SXP 10.3.x PRE builds; includes automated application of binding redirects and patching of config files where applicable; see Documentation/Optional deploy automation/readme.md in the SXP 10.3.x PRE build package. |
| 592307, 592301 | Internal link to a versioned media item added in RTE contains the wrong language using Sitecore Link via Search when languageEmbedding setting to "always" |
| 580597 | Media URLs containing encoded characters (e.g. hyphens for spaces) are not properly decoded during resolution. This causes Sitecore to fall back on a slow traversal of the Media Library using MixedItemNameResolver , which significantly degrades performance in large, deeply nested media structures |
| 576714 | The ModularTrafficAllocation processor can cause a lock convoy under heavy load due to inefficient concurrency handling in its visit count storage mechanism |
| 559176 | Deleting a large number of archived items via the Recycle Bin UI or Archive API is slow and prone to SQL timeouts because it's done in a single large transaction, which rolls back entirely if interrupted |
| 536792 | Adding HTML cache records is not thread safe |
| 458558 | Anchor fragments (#) in links are stripped during email dispatch, causing links to ignore in-page anchors. This is due to the MapHostname processor not preserving the fragment when rewriting URLs |
| 438400 | When the RequireLockBeforeEditing setting is set to false, non-admin users with appropriate permissions still see the "Details" and "Reset" buttons in the Presentation ribbon disabled. This prevents them from editing presentation details, despite the configuration explicitly allowing edits without locking the item |
| 384689 | When a rendering that has been personalized is deleted without removing its references, attempting to open the associated page in Experience Editor results in a yellow error screen. This occurs because the editor fails to handle the broken link gracefully, throwing an exception due to a null ContentDatabase |
| 370121 | Under high load, frequent use of Sitecore.Globalization.Translate.TextByDomain(...) to retrieve dictionary values can cause a lock convoy, due to synchronized access to a shared Hashtable in DefaultTranslate.Domains |
| 356688 | Sitecore.XConnect.Segmentation.SegmentationEngine.PerformSearch lock statement blocks threads if the xConnect search response time is high |
| 290139 | Requests with illegal characters in the URL cause the XFrameOptionsHeaderModule to throw an unhandled exception, resulting in a 500 error instead of a proper 404 response |

| 615909 | Increased lock contention when writing log messages during web requests |
| 615496 | Sitecore.Caching.RenderingParametersCache subscribes to some events without checking if it was already subscribed at creation time, which causes an incorrect behavior in LinkManager and performance degradation. |

| 591676 | DateTime fields are rendered in UTC time instead of server time |
